My Ford truck tires are 275 70r18 if I went with a 17 inch rim. What's the biggest tire size I could go with?

Hi Joe,
The 17� size cross over for your vehicle is 295/70R17 you could probably put a 315/70R17 on it but it would need to be fit checked prior to fitting all four. You also need to verify the 17� wheel will clear the brake caliper on your Ford some of the trucks were boosted to the larger wheel so a larger brake could be used on the truck. You didn�t give the model or year of the Ford or if the truck has stock or lifted suspension so it�s kind of tricky picking oversized tires without having the truck and doing some measurements.
