Difference between front and back tires
If the total diameter between the front wheel/tires and the back wheel/tires excedes the allowable difference, I know the speedometer will be wack - what else goes wack, ABS???

If the rear tires are the same diameter or smaller than the front your traction control system will activate at very inopportune times. Generally speaking you want to keep the rear wheel/tire combo 1/2 to 1 inch taller.

In your example, with the rear tire's OD being "too small", the computer preceives this as "wheelspin", and the traction control activates, reducing power, until traction is achieved. However, since the tires are the cause, and a constant, the problem can't resolve, so you'll be in reduced power mode all the time.

rims are 9.5' wide .. front tires are 255 35 20 , and the rears are 275 35 20. The fronts rub a little when i go over a speed bump only. i will fix the issue when i install my tpe t2 flares, i will install lower profile tire at the front and 345's at the rear hopefully
