MONTE CARLO WHAT TIRE AND WHEEL SIZES

[Bruce Compton]

The new project is a 78 Monte Carlo 305 and a 4spd. Going to be strictly a cruiser and driver. I would like to use 15" wheels and tires same size all around. What are some specs not to wide and fill up the fender well
and not hanging out of the fender?

235/60/15 seems to be a good fit. That's what I was & will be running on my '81.

Currently on my 79 I have Torque Thrust with 235-60's in front and 255 60's in the rear as was on the car when I purchased it. I changed to 15 x 8.5 in front to match the rears. The 255's in the rear just catch the fender lip on the left rear only. To put the 8.5's in front I had to heat the inner fender at the bottom and remold it closer to the frame. The 15 x 7 Torque Thrusts that came on the front cleared with no problem with the same 235-60's. I've also had the 15 x 8 Corvette rallys from my 88 SS with a 245-60 tire and the cleared without any rub.

USA-1, Can you tell me what back space is on the wheels?

 

[79 USA 1]

The Torque Thrust are 3.75 for both the 15 x 8.5 and the 15 x 7.
The 15 x 8 Corvette rallys are 4.0.

Thanks. Your car looks good.

I currently have 225/60/15 on 1978 corvette rims. Not a single problem.
