Tire Purchase


50Dodge

Recommended Posts

Ok, I am getting ready for some new rubber for the 50 Coronet. When I bought the car it had/has air shocks with 235/60/15. I have to keep max air in shocks or they rub the fender lip. My original spare looks to be a 7.10  which I converted using your guys' references to be either a 215/75 or 225/70. I would like to run the 225/70 as they are a little shorter and wider. My plans will be to then drop the rear 1.5-2 in. Does anyone see or have had any issues running 225/70? Pics would be appreciated also.

measure your rim...most run 205 on the narrow rim....if you have the wider rim of that era, you can go 215....225s on the wider is a bit of a push....but then, that is my perspective.   Here is a base line as used by tire retailer for tire size verse width....

Running 225 75 15 radials on 5.5 wide aftermarket wheels. Pretty close to 600 16 diameter. Have 205 on the front but they are too short for the rear, and throw off the speedo off by nearly 10 mph. My rears used to rub with weight in the trunk going around turns.  New shocks and spring to bracket bushings cured 99% of that depending on how much stuff in the trunk.  Also my springs have sagged so the rear is lower than stock.  The problem with wider tires is being able to jack the car up high enough to get them to clear the wheel openings when you need to change them. Sometimes a real 

Ain in the butt if dealing with a flat at the side of the road.
