Need meat in the middle for a longer lasting tire!

Post by Clogan » Sat Apr 14, 2018 10:09 pm

KTM recommends Angel GT, spec D for the SDGT. Mine rear tire needs replacing after only 4000 miles. It has a 3/4" strip, right down the middle, worn down to threads. There's plenty of tread left all over the tire, but the area right in the middle, where there was no tread or grooves to start with, is worn out. Im guessing the tire carcass must have been less than 1/8" - 1/16" thick in that area to start with. I'll measure it when my new one gets here. Guess I spend too much time going straight, and not enough time leaned over!

Anyhow, its sad to see an otherwise good tire have to be replaced due to that 3/4" strip.

Unfortunately, it appears to be a design characteristic of many sport touring rear tires: the tire carcass is thinnest, with the least tread, right down the middle. No meat in the middle. I'm guessing that if the carcass was as thick in the middle as it is along the sides, we would easily double the highway miles life of the tire.

Mine still fine around 6,000 miles, worn of course but still got some life in them. That's after a hot summer, some and using the power on some coarse country roads too. Weird.

I will be trying Michelin Pilot Road 5 next though, as generally prefer them especially for Winter.

Moved to the Angle GT A Spec. Same performance but, a more durable tire tread for the heavy Sports Touring bike. Best,

That's good to hear about the A spec, since I expect that's all most shops would carry anyway.

GT are not really that heavy .. my mates z800 Kawasaki weighs more !

Though I guess if you tour with a pillow and luggage most the time it would load up the rear tyre.

Mine is mostly commuting with light luggage, so I think the Michelin tyres will be fine for me.

The A Spec is a heavier tire and has a stiffer sidewall. Just know that going in. Gary runs it because that’s what the BMW 1600 uses. Gary probably has his own “group buy” on them ;)

I personally would not run it on a bike that doesn’t need it. But then i cannot imagine the middle of a regular Angel GT wearing out at 2,000 miles.

Look forward to your comments on the PR5, I’ve run the PR4 on my multistrada, I found the front a bit vague so swapped it out for a Metzeler O1. And the PR4 rear was fine and good in the rain. I’m thinking of the PR5s for my next multi tire, but I’m putting something more grippy on the GT, was thinking of trying the S21s.

Hi all,

I've run with PR4's eer since they were released and never got less than 20,000kms to the wear indicators ( fuk where's that calculator buried on my desk......oh right....12,500mls)....... and that's the tyre I'd recommend for anybody doing lots of long distances on fairly straight roads as it has a strong centre tread and is good in the twisties/wet as well.

A PR5 on the front would be much better than a PR4 front.

I suspect the PR5's will be a little shorter on mileage, but much better on sports grip than the PR4's....... still good mileage but just a bit better performance for those with lots of nice tight corners nearby... ;).

I'll keep watching for all the PR5 comments while I'm scratching my navel instead of my GT..... :lol:

Ps The Gt is quite light (book says 233kg wet - full tank......err, add any accessories, passengers, luggage) and if you use that throttle in anger the rear will disappear fast....... just like the cars trying to follow.. :mrgreen:

My Angel GTs were nearly dead after 5500km

Also had a nasty cut on the rear tyre so changed to Roadtech01 after so many had good feedback. Was intrigued by the T31s (also had a 30€ cash back) as I loved my T30EVOs

Now I am nearly at 13k km with 360° riding including highway dashes at over 160kph, Alpine passes, commuting and lots of rain.
They are very well worn and I guess I can take them another 5k km at least.

In end of July I will do the first 15k km service and change the tires for Nordkapp
Will stay with Roadtech01s

Maybe next year during the spring/early summer I'll try tracking the beast but I'll need to buy all the equipment and maybe try an agressive tyre like the D212s

Morning there eXiLe88, I've firstly run the Angles=5200kms, then fitted the M7RRs=3600kms, then 2 sets of Roadtec01s=2x7500kms and now the PR5s=200kms, the PR5s feel really good, i liked the M7s but they wore too quick, the Angles were good overall, the roadtec front was a great tire, the rear was a slow turning tire but excellent in the wet and great grip in the dry, but i think the PR5s are going to be my pick, early days yet, but the signs are good, The PR5 front is a much improved tire over the PR4 with a more neutral tip in feel, but the rear on the edge grip feels like a sports tire, giving great corner exit grip, I'm enjoying these tires so far. GT has now done around 25,000Kms and going great.
