I've searched the site and came up with less than nothing...

I had new wheels/tires installed today, and as soon as I drove out of the tire center, I noticed the service engine soon light came on. They were closing so it was too late to go back.

FYI... I went from OEM 18" wheels/tires, to 20" wheels and 305/30 rear, 255/35 fronts. I checked the diameters, and OEM are 27" front/26.7" rear diameter, new tires are 27.01" front/27.24" rear...

I assume its the differences in tire diameters, but I thought as long as the difference between front to rear was less than 0.3", I'd be fine... the fronts are almost identical to OEM, but of course the rears are a good bit taller than the OEM rears... but from front to rear, it's only 0.23" difference...

Can I fix this without having to buy new tires? Will it harm anything long term to leave it as is?
