    Question Largest Tires on a mid-80's Sedan DeVille?

    I have an '86 SDV that still has the stock 205/75-14 tires/rims. I want to go to 16" wheels, but I also want to get the most rubber too. I.E. I don't want to go with the low profile 215/60-16 that is recommended by Tire Rack. I want the old school dookie tires we used to love in the 70's

    My question is what is the largest tire anyone has used on a similar vehicle without any problems. I want to go with 16" wheels, but I'd like to hear from anyone with 15" or 17" too. Also, please let me know if you had to raise or lower the suspension to accomidate the tires.

    Are you looking for rims and tires?

    I sure you could go with 225-35-18 or maybe step up to 245-35-20. I have 20's on my car and love them. I have no probs what so ever. Prior to running 20's I had chrome 95 Eldorno wheels with 225-60-16 Michelens whitewalls tires.

    If you plan to go big make sure your suspension is in good working order.

    You're right, I do need to do the suspension work first. I know it needs rear shocks and springs, and I might as well replace the front shocks and check out everything else.

    I am going to replace the rims and tires at the same time. Still have the 14" stock rims. I want to go with either 15" or 16", but I want tires with the tallest possible sidewall. I know, that's the opposite of what's fashionable these days, but I'm old-school. Going for the "balloon tire" look

    I think what I'll do is get the suspension up to par, then measure the clearance with my stock rims/tires. I found a calculator on the web that will give you the total diameter and width based on the tire and wheel size. When I figure out what I can safely go with, I'll post my results, along with some other wheel/tire sizes that would be equivalent.

    Thanks,
    Scott
