hey guys im new here. Ive read the sticky and searched but can find my answer. I got a 04 sedan with 245/35/20 8.5" wide rim up front and 255/35/20 9.5" wide in the back. When i take a turn at high speed the slip light goes on and if i go too fast the abs kicks n i think. If im turning right the left front brake kick in. I took it to an alignment shop and they said the tire combo is throwing the geometry. what do yall suggest to fix this?

 

Tire Size Comparison

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
235/40-20 3.7in 13.7in 27.4in 86.1in 736 0.0%
255/35-20 3.5in 13.5in 27.0in 84.9in 746 -1.4%



Odd, I would have thought that 1.4% would be okay.

 

well the front is 245/35 not 245/40. Im on stock suspension. I think they told me since the rear tire is a 255/35 it raised the rear of car up. So that the car has more body roll now. They suggested that i use stiffer springs of course that would mean lowered springs. Is this correct?

 

Alignment guy doesn't know

1% even closer

 

well i say alignment guy but the shop had their nissan tech test drive it. When i swapped to my new wheels i had 245/35 all the way round and since the rear is 9.5" the tire was stretched and it didnt do this. I wanted to have a wider tire in the rear and when i put the 255 on the suspension started to act funny. It doesnt feel as stable around turns and at high speeds.

 

anybody?

 

Is your G AWD? That could explain the issues if it was and you were running staggered with two different tire diameters.

 

no its only 2wd

 

anybody have any ideas?
