Default Tyres - general feedback and opionions

Hi guys,

Well this is just a start for some feedback and opionions about tyres. The use will be mainly for street... and yes I enjoy driving with a quality tyre.

I am looking for some bigger tires for my harrison. Currently running 235 45 17 and 265 40 17 Yokohama AVS. Awesome tires and I have no complaints however time is comming to go bigger to fill these guards.

I have used many different tires in the past however looking for any feedback that you may wish to comment on.

I am planning to go to 245 45 17 and 285 40 17. I know that you can get 315 35 in the rear however I would expect that this would depend on the brand as the pic below is a comparrision of 315 35 17 for a Sumitomo and a Goodyear eagle show is the size difference.

Happy for any feedback from other harrison owners and their setup.

Has anyone used Continental Extreme Contact?

Thanks in advance for your comments.

Cheers.

I have the Conti's on my Audi, and they're very good - so good that I renewed them when the first batch wore out even though there were cheaper options.

What are your rim sizes?( Widths)

That will dictate what tyres will fit .

Cheers,
Warren.

Leroy, I beleive the tyre width (ie 315) relates to the tyre being on a particular size rim not on its own. I would expect if you put both those 315 tyres on a 10" rim they would be the same width as the bead will blow out to seal on the rim. I have the sumitomo on an 11" rim and they measure about 313mm. The shape of the wall will make a difference from that angle as the actual tread width may vary, but the width of the tyre is the width for guard clearance.

Thanks guys.

Currently have 8 1/2 front and 9 rear. I am looking for OZ wheel to increase the rear to 10 and change the offset on the front for a bit more dish.
I know that the 315 Sumitomo will fit on a 10 and will have clearance (i have done measurements for this) however do not know much about them, this is why I was leaning to a continental 285.

Thanks for the replys.... appreciated.

Cheers.

Do you guys have max rim sizes up there?

In NSW, the RTA have a document that specifies rim sizes based on vehicle weight. For a cobra, the max rim size is 8inch due to being under 1200kgs. Apparently its due to aquaplaning. Im not sure if they actually enforce it though as there have been a lot of cars with wider rims (including factory cars) registered since its release.

The 315 is not a good fit on a 10" rim in my opinion. The sidewall is definitely pulled in and I reckon you loose some tread footprint from this. It's an ideal fit on an 11" rim.

These are Yokahama ADVAN 315's on 11" rims



These are Sumitomo 315's on 11" rims. Note the nice straight sidewalls on both tyres.


Cheers

I have Kuhmo KU36 315/35 R17 on 10.5" rims. Here's a photo of them. The tyres are pretty good from what I read on forums.

Interesting to note the difference in rear wheel arch flares between the 2 different bodies.

I hear good things about the Kumho KU36 as well. A set will be on my shopping list soon.

Cheers

Leroy17,
I have Kumho 285/40/17's on the rear and 255/50/17's on the front. On my Harrison they fill the guard nicely with a similar gap from the lip of the guard to the top of the front and back tyre.

If you live around Brisbane try this company. They can usally supply Kumho's slightly cheaper than the delivered price from the Tirerack.

Now time for a tyre report.
As most know I replaced my tyres with the KU36 before I headed off on my trip.
Well after 5100kls driving in heat (39 degrees) rain (110mm) course blue metal highway and rough potholed highway, I can report I like em.
In the rain I never had an aqua planning concern (although some "puddles" where so big that the water came off the front of car and over windscreen) and I was driving at 100 - 110kph.

Here is a pic of a new tyre.

Note the name in centre and thin groove on R/H (outer) side of tyre.

Here is my front tyre.

Although hard to see the name in centre is just there and teh groove is plane to see. I would estimate about 1mm worn.

Here is the rear tyre.

The name in centre is gone and the side groove is just visable (groove is gone).

Tyre pressures where set at 32 to improve comfort.

I have run Goodyears before but just recently purchased the Vredestein Ultrac Sessanta. What an awesome tire. Below is a few forums that review them if you are interested.

http://forums.corvetteforum.com/c5-z...out-these.html

http://www.m3post.com/forums/showthread.php?t=268043

I run 245/45/17 in front and 315/35/17 on the rear. I just purchased them about a month ago and love them. They stick to the road and give a great ride. Not sur eif htey are available near you but I purchased mine thru Performancetire in california. They were great to order from. For the price it is worth a look.
