I'm thinking of putting some Nitto 305 / 45 / 18's on the rear with Stock F1's up front.

I read somewhere that different sized tires between front and rear will make the ABS computer freak out as the tires are spinning at different rates.

Is this True? How do you correct it? (besides reburn chip) is there something to disconnect with a SES light going off.

When I run slicks 28" at the track I don't get any errors. These Nitto's 305 / 45 / 18 are about a 1/2 inch wider and 1/2 inch taller than the stock F1's.


Anyone?

 

I don't see why the computer would care - when you go around a corner the wheels are turning at different rates of speed.

I have not tried it, but logic tells me there is probably a window of margin that, as long as the wheels operate at speeds within it, everything will work fine.

When you power brake the fronts are stationary and the rears are hauling @ss - that doesn't set a code.

My $.02, for what it is worth....

 

Haven't heard of any issues, and many on here are running the 305 555R's with the 295 555's up front. This is what I plan to do as well.

 

I run that tire combo. Have had them over a year now. No issues whatsoever. Even the wet weather performance is fine.

How do you like the traction compared to the stock f1's?

 

Street traction is much improved, especially in the warm weather. With approximately 600 HP on tap my F1s were worthless and wouldn't hook when punched up to about 50 MPH. The DRs will grab at about 30 MPH and above.
I can't hook at the track with them at all at my power level. I overpower my 28" full slicks and just bought 30" M+Hs.
