Wheel and tire seems always hard to find with complete information. Many omit many of the details I am looking for, Rim, Tire size, BackSpace, fender lip rolling, drop, non-stock suspension, etc.
I have a stock 68 Conv 350. I currently have 225/70R14 on all wheels on stock 14" Pontiac Rallye II's (14x6) with 4.5" BS, 26.6" Diameter. I think my front springs are worn and I have had some scraping on the front wheel well moldings on heavy potholes while turning.
Reading other posts I have seen that 26" wheel diameter seems to be a good starting point and should work on the first gen.
I am putting disc brakes on my front wheels and going to 15" Pontiac Rallye II rims (15x7) and I want raised white letter tires too. I am looking to stick to around 26" tall wheel. There are 2 companies I have found for RWL and I only see 14" and 15" mostly.
I am currently installing RideTech's Street grip and I am looking at the following options (BUT I CAN'T CONFIRM IF THEY WORK YET)
Options I am looking at for the 15x7 with standard 4.5" BS Rallye II's. I am concerned about the drop that I expect to get with the StreetGrip springs and leafs. My biggest want is the width to get the most tire on the ground to for the most traction that will fit in the wheel well.
Possible sizes (I will update in the spring after I get the suspension on and the car off the lift) Front: 215/65R15 225/60R15
