So how are you guys handling the 2% inaccuracy in the speedo with the shorter tires. While 2% may not seem like a lot, as the tire wears down this error increases. I am assuming the speedo is based on the rear tire's height, nothing to do with the fronts?

You can tune to fix or honestly it is so small I would just leave it. The difference is so small there is actually more of a difference between worn out tires and new tires. Bald stock Pirellis are actually smaller than the 295/35 20s Taylor is running out back.

WOW. i had to idea the tires i just got were this good! the guy at my local placed recommend them so i went with them.

i went with 315s.

This is the best setup I've seen. Perfect tire diameter and width, awesome stance, and the black graphite turned out awesome. Very nice!

I'm getting the Super Sports in 29530R20. So, smaller sidewall. 27 inch diameter tire. In the end it's got to be a balance of lowering on the coilovers and lowering because of a shorter tire. To me the only number that makes sense to compare apples to oranges is air dam ground clearance... how many inches between the lowest part of your air dam and the road.

I am thinking about 3 inches is what I'll try out. Got a number you could share, just for comparison?

Peter, when I build various cars for shows and road use, I always try to maintain a minimum road clearance of 3" from the lowest point of the vehicle. So, that is a good number to shoot for. But, I've driven a car with 1.75" clearance across the country and back. Scrape city! haha

Yeah I know you can tune for it, just wondering if it was enough of a concern. But your point about bald Pirellis is just as true for the Pilot, which make the inaccuracy even worse as they wear.

I like this tire a lot though, so I'm probably have my tuner tweak my tune for them. After yesterday's high-speed autoX I really need to dump the stock P's. They didn't seem too bad until I took off traction control in the timed portion. When I pushed the pedal in some of the faster turns all I was doing was spinning the tires coming out of them. The track surface temp was only 63, but I thought they should have done better.

TaylorRyanSS · 04-22-2012, 02:50 PM

I am 5 inches from the lowest point on my car to the ground.

mikeyroche · 04-22-2012, 03:24 PM

I still find it odd that they make a 245/45ZR20 but don't have the 275/40ZR20 size

+1 I would def be rocking these on my new rims in a 315/35 & 275/40 setup if available.

Crowley · 04-22-2012, 04:12 PM

Hey OP .. if you get a chance .. pm me on how you like these . .I'm doing the same Combo on my GT500

.. going through whiteside as well and he talked me in to these vs the Nitto Invos (275/40 and 315/35s)

. I know it is going to be a great tire but just wanted your impressions.

BTW .. looks great!!

I may be doing an autocross event on May 5th so that will be the real test lol. But so far for street driving they are great, very good grip and it really sticks when you corner aggressively.

Wow, that is a ton of ground clearance. On my drag radials and skinnies three lowest part of my car is 2".

Camaros aren't the only ones that use that size.
