Tires with Whipple Stage 1

[HSteel57]

Taking my S650 in next week for Whipple upgrade. Still using OEM 255 40R19 tires but upgraded to 19x9.5 wheels. Anyone who's done this mod, did you have any luck/make a difference changing rear tires to 275 or 285? Thanks!

Compound is what matters, not width as much.
A lot of guys go with 555R2 nitto or Toyo R888R, MT et street SS is also great.

my car is whipple stage 2 and I drive around on stock 255s most of the time, the traction control works really well.
I use a 28/11/17 bias ply Et street R to hook at the track/ street fun.

Must be a different animal but my ZL1 with only 650/650, the 305 were barley enough, with sticky tires.

Keeping traction control on will save your tires

and your insurance. and your money. and maybe even your life. basically, never disable TC let alone AdvanceTrac once you supercharge. recipe for disaster real quick

I know of several 1700 hp cars that put in work on a 275 radial pro

Agree. Ran 315/30 Hoosier A7 in my SC pony and they'd break lose quite easily. All about control and throttle management.

This is why compound over size
A7 compound is for auto cross on cold tracks

Among other styles of racing............

 

[Q6543]

No, it’s a single purpose compound for cold temp auto cross.

OP put a R888R on or ET street SS if they have your size.

 

[RLE55]

No, it’s a single purpose compound for cold temp auto cross.

As I said: among other styles of racing

 

[Q6543]

Ok, you bought A7s and had problems hooking up, holding power.

You’re complaining about it while debating its uses? I don’t get it.

Complaining?? You obviously have me confused with someone else as, I was only pointing out your comment about A7's being, "a single purpose compound for cold temp auto cross", was not entirely accurate. And, I never said I had problems hooking up, holding power. Once the A7's heated up they did very well, good enough that I ran them for nearly 10 years road racing. My whole point in thread #7 was to point out it doesn't matter what make tire or size you have, a high HP & TQ car will still break them loose. I'm done, time to move on................

Thank you for the great info! To finish the thought, been driving with the Stage 1 Whipple for a few days now. Really an amazing upgrade, but requires some care . Tires spin but (so far) only in a straight line. It's possible traction control isn't functioning properly? - but sure that it's turned on along with Advance Trac. Will probably keep the OEM tires for now since I do more driving in the wet than doing burnouts, lol.
