I'm looking for some reco's on tire size for my '89 Cavalier (Hobbystock/Hornet class). The car currently has P185/80R13's on it & I have a spare set of P185/85R14's wheels & tires. The guy I bought the car from threw in a pair of P185/60R14 tires also.

I'm thinking that I will install one of the 60R14's on the left rear. Is that a good idea? What about the right rear?

I think I already know the answer to this question but do both front tires have to be the same size? In other words can I install a 60R14 on the left front & leave an 80R13 on the right front? Is it better to have taller tires on the front or shorter & fatter?

Any help would be greatly appreciated.

from my experience you want a bigger tire on front right when you go in to corner and you car leans it will push the left rear back to the ground i run all same size tires just change air pressure i run about 5 pounds more on my front right then my left rear.

Holy **** Dunn thats some low pressures for dirt. Granted I have a bigger car but even the little hondas run more than that. From what I've been told by all the top guys you want about 30-35 in the rears to get the back end loose and about 35 in the front to get maximum traction. You can offset the front from side to side depending on the size of car.

About that cavalier...I would run a 185/70/R14 or a 195/70/R14. The lower the profile tire the better...less tire roll. And if you can run different size tires then I would run the 60's on the left side.
