I was messing w/ the wheel calculator... Going from 245x45x18 to 285x30x19 there is a 3.6% difference with the speedometer being to fast. Now from 245x45x18 to 285x35x19 the speedometer reads 0.6% to slow. Is that calculator off or is the 35 a better match on the 19's for the rears?

Thanks man
peace

He's right. There is no way you can run a 45 in the front with a 35 in the rear. The set up should be 245/35 front and 285/30 rear. That will put you to 0.1% too fast which is the closest you can get to perfect.

actually the numbers represented were for rear tires in both cases. The calculator was saying the 35's are a closer match to the originals than the 30's. I wouldn't even consider 45's in the front, 35's is the size for the fronts... just wondering on the rears from 30's to 35's.... 45's are the size of the original tires on there right now.
