Title: TKC-70
Post by: Charleston on March 19, 2017, 09:54:30 PM
I have read several reports of front wheel wobble with the TKC-70 tires. Has anyone experienced this with the XCX?

Thanks.

I really want to know to because I'm considering installing them soon...

There has been posts on the S10 forum about the front TKC70. Not sure if it's the same issue.

It's been a  week with no replies, so I ordered a set. I'll post if I have a problem.

Most of the reports I've seen have been on the GS.

I'm running TKC70s on my '11 Roadie. No wobble or whatever. Great in the rain and much improved traction in dirt and gravel compared to the stock tires. I think you'll like em.

You will not be disappointed, they are great tyres in the wet and even better in the dry....peg scratching good!! :007:

Yep, the TKC70's give my footpegs a rough life..!
Good in the wet, great in the dry.
Must say that the front tire is cupping, 8.000 km's old. And the front is a bit noisier at low speed. Also you can feel the knobbed profile working a bit better at low speeds.
But for me, these are no issues.

Good dry and wet grip and capable of doing off roading is what counts!

Cheers,

Dennis

Just completed a 1700 mile trip, probably 500 miles on 2 lane mountain twisties  and 800 miles on interstate. Tires performed flawlessly, no wobble or bad behavior, wonderful grip in the twisties. I am thoroughly happy with them.

If the front is a cross ply that is quite common particularly when the tyre is cold. Its to do with the construction rather than the actual tyre.

Not with the TKC-70 but with the 21" front Metzeler Tourance.... A very sad affair.. Wobble at any speed below 100... Never again. Great grip but you can't take the hands off the bar. Just thought to pass this on... :151:

Just about to change my set of TKC-70's after about 16,000km. Found them great on both road and occasional dirt/gravel. Great confidence in the wet and much less prone to tracking on cracked tarmac etc than the OEM Scorpion Trails. Reasonable amount of tread left on both, but front cupping started about 13,000km and the noise is now unbearable, hence the change. Thinking of going back to a more road oriented tyre - any thoughts on Battle Wings?

Fitted and balanced myself a tkc 70 in place of a ruined Scorpion trail 1 yesterday on my xc. Easy game.
On the road I didn't notice any noise or shimmy, just easier to turn. On gravel he is more stable and comfortable, despite inflated to the same pressure (2.4kg). But on light mud it's really night and day, no more permanent sliding, I can run a lot faster feeling safe.

Very happy with it, so far I recommend it.

Well I have had TKC-70s on my XC for around 5k miles and have just noticed wobbling at the 96-98mph mark- haven't had the b**ls to see what happens above that. It is very noticeable at the front end, tried with and without my top box on the back same wobble, otherwise unladen. Front pressure at 2.5. bar. Don't think i had taken it up to this speed before on these tyres until recently but had done so on Conti Trail attacks before with no issues. So I wont be putting TKC-70s on again. Trouble is they wear so well it will be ages before I change and I don't make a habit of tootling around at these speeds so will bide my time. Absolutely no issues below that speed and they grip well, wear well. Perhaps a bit less smooth at motorway speeds than road tyres, to be expected.

Obviously you are only using the tyres and those speeds on a track day so might be best to get yourself a new set of wheels fitted with some Pirelli Diablo Rosso Corsa's for such occasions. On s serious note, you may find the TKC70 is not speed rated for the higher speeds anyway and therefore could de-laminate!!

Of course wouldn't do this on UK roads but they are V rated so technically to 149mph without delamination I would hope. To be fair on Triumph however they have not homologated these tyres which were not available when the 800XC came out, and to be fair on Conti they are designed to be compromise between road and off road use so fair dos if they don't like track speeds. But the OP asked if anyone had had wobble at speed on these tyres on the XC and I for one have.

The 21" front TKC-70 is T rated. 180kph.

Just so, thanks for the correction,  its the rear that's V rated.

I have recently installed TKC 70 front only and Mitas E07 rear. This type of combination (TKC70 front) is very common amongst the adventure bike fraternity here in the South Island of NZ. There was a shortage of TKC70 21” here in NZ earlier this year. The real debate here in NZ is what you put on the rear. As we know there is nothing scarier than losing the front and nothing more grin inducing than braking out the back in gravel in a controlled power slide. I like the four-wheel drive tracks and stock route and the non-tar seal available in my backyard so my bike spends resonable time in the dirt.
As for wobble, absolutely nothing. Taken the tyre to its speed rating of 180km/hr. I was sceptical about the performance of the TKC70 with its open block tread pattern. As other threads are saying you can still rub your pegs if you feel the need! I am riding winter roads, the TK performed well in fresh snow over one of the passes recently, it holds very well in all condition on and off, I was very surprised their stability on gritted roads the open tread block clearly assists. The back tyre twitched a bit in the grit but that was possibly power related.
They will fill with sticky mud, as any other tyre does, so be mindful about your mudguard clearance if you are trying that sort of riding.
I have had heard of people riding with TKC70 on a cornering track day and the disbelieve of other riders when they try to beat the TK rider is very funny. “You can’t do that with that sort of tyre!” :013:
Regrets, yes not binning the OEM tyres on day of receipt of new bike/s, one (Pirelli Scorp1 and Bridgestone BW) positive is at least having run the OEM tyre I know how much better the bike is with the TK70. I have also have had two sets of Heidi Scouts before the TK70, Mitas E07 combo, the Heidi’s were stable and hard wearing some people do Heide Scout rear and TK70 front. I think my current combination is better than Heidi front and rear. I only have travelled 4500 kms on the TK/Mitas combo so far yet managed to have put them through all conditions. So I,m a Happy Chappy.
Note hearing good things about the new TK80, for those wanting a less aggressive tyre more road but still want to do gravel from time to time.

I think you mean the Trail Attack 2 as the less agreessive road oriented tyre. The TKC80 is essentially a knobbly tyre for ADV bikes and is proabably one of if not the most off road oriented ADV bike tyres on the market.

Thanks KIWI, Oops everyone that was an own goal with my thread I mixed up TK70 and TK80, actually running TK80 front and Mitas E07 rear. If you read my thread with TK80, and yes the aggressive front knobbly 21" trye is an amazing performer both on and off road.  :430:

12000 miles now. Front is cupped and noisy but still performing well and has plenty of life. Rear could probably go another 1000 but I have to put on a new chain so I'll replace both tires at the same time. I have been very pleased with the TKC 70 under every condition and can't think of any reason to switch.

I've been running TKC-70s for a couple of thousand miles - so no comment on longevity yet, but nothing but praise for the feel on everything from smooth fast twistys to scabby broken backroads with gravel & grass. No wobbles evident. I thought they might feel a bit knobbly on tarmac compared to the Anakee 3's they replaced, but seemingly not. They work for me!

Greetings. Just ordered a set of TKC70's for the front and rear for replace the Metzlers which gave me 10K miles of service. The tyre construction was one reason I opted for the radial 110/80 size instead of the cross(bias)-ply 100/90 size for the front of my XRx. I gave up a little off-road performance in terms of the slightly wider front tyre, but since I am only looking for a bit more lighter off-road action, I felt that it was a better choice in my case (and for the XR version). Anyone else have a comment on running the 110/80 over a 100/90 in the front?

See https://www.revzilla.com/common-tread/why-things-are-bias-ply-and-radial-tires for a good discussion on construction.

I have replaced the OEM 100/90 tyres with 110/80 on both Tigers I have owned and would never ever go back to the 100/90. The change transforms the way the bike handles for the better on sealed roads and despite plenty of dirt road and gravel road type riding I have never found a negative impact in those situations.

Whilst your comment is well taken and you obviously enjoy your choice, handling remains a somewhat nebulous term. Few, is any, are the ways in which to quantify handling.
Like a similar discussion elsewhere on this forum about different sized brake master cylinders improving braking, it all comes down to rider preference.
Change in braking can, though, be quantified by measured stopping distance -- handling, not so much.
Interesting, too, that Triumph see fit to still supply the latest Tiger800 models (the more road oriented) with 100/90-19 front tires. And all Tiger800 models with bias play front tires.
Makes one wonder Triumph's - engineers' & test riders' - reasoning? I've a hunch it has to do with the bike being an "all-rounder"..?

TKC 70's are good for the price, but not much better than the far cheaper Shinko 705's.
They are a good on/offroad tyre, but NOT the best by a long way.
I have done more long distance travel on mine & after about 8k miles on the front the noise is unbearble & the high speed handling has become suspect!
They are also cupping.
The Shinko's are exactly the same, yet way cheaper.
If anyone wants the best on the market at the moment, try Pirelli Scorpion Rally STR's.
The price Is Right!

Having run TKC70's, i will never go back after running the Scorpion STR's. They cant be beat in my opinion for longevity, handling (on and off road) and price.
