As long as the overall diameter is the same you can go down to a 14 inch wheel.
You can change the wheels to a 17" without modifications.
Recommend Rollbacks only
Not without modifications to the suspension.
Not without major modifications.
The shocks on a 2000 Ford Ranger are replaced by jacking the vehicle up, removing the wheels, unbolting the shock, and removing it from the vehicle. Because the vehicle is supported off the ground, the shocks are not under load and can readily be replaced.
you can put twenty inch wheels with low profile tires without modifications. any bigger you will have to cut the fenderwells and tweak the suspension to raise it otherwise.
yes.
The answer is yes. They both have the same bolt pattern 5 x115. No mods whatso ever
Yes, with slight modifications.
No, but there is some that are very close to fit and is not appropriate to install them even when you can put them on, an lease you do the appropriated modifications to it.
NO. They are goinf to scrub when you turn the wheels unless you do some serious modifications to the wheel openings to give the wheels more room., and I don't know if you will get enough room even then.
If your 2000 Ranger XLT is a 4x4 and has the 16in. stock wheels, the tallest tires you can install without rubbing or modification are 235/85/16. With 15in stock wheels the 32/950/15 is very close. You may have to modify for these. I currently have 235/85/16s under my stock 2000 XLT Ranger. Goodluck.
