what brand it comes with from factory?

whats the best after market size to go with?
19'' in front 20" in the back 325/25/20? will it fit?

thanks

 

The R8 is AWD. I don't know if you can mix wheel diameters. Go to www.audiusa.com or www.tirerack.com for tire sizes. Rear OEM tires come in either 295 or 305s depending on wether the wheels are polished or not.

 

i see.

i think a have seen 19 in front and 20 in the back in r8. same way as callardo and murcie. i guess u just have to make sure diameters are ok

 

PS2 are great tires.
or get Nitto INVO. it offers great performance but won't hurt your wallet as much.

 

As long as you do the math and research, you can have different sized wheels, but quad check the tire heights and numbers before you put them on. The results of this could be blowing up your drivetrain (tranny and diffs) if the numbers are wrong.

Ive seen what happens when you dont. Punk teenager with lots of money and no brains put on different sized wheels on his 4X4 truck. Once he put it in 4WD, he made it 4-5 miles before his transfer case imploded.

 

We just finished installing a set of Michelin Sport Cups on stock R8 wheels for a local customer...But I would recommend Michelin Pilot PS2 235/35/19 & 305/30/19

 

I agree!!.. I would say Michelin Pilots or Nitto 555r...

 

Nitto Invo tires are better than the Nitto 555

 

thanks everyone..

i have ps2's in my porsche and just love them.. cant go wrong.. what about sizing. where i can find charts/website that tell diameters of different size tires?

 

Here is a listing of the sizes on the PS2s. More than you want, I'm sure

I know a few R8s with HREs in 20 in the back, 19 up front. Ben at Wheels Boutique is running 21 in back, 20 up front. I have 20/20 with my HREs, with 245 up front and 315 in back with Toyo T1R on my street wheels. I don't know about 325 though. For the track I am using OEM wheels with 245 up front, 305 in back, Toyo R888s.

The OEM tire is the Pirelli PZero, which a decent tire but not as good as the PS2.

 

Keep rolling diameters within 3% and you should be good to go
