The 245/60/14 tires I have on the back now look too small and barely fill in the wheelwell, so I am thinking of going to a 255/60/15 on the back and a 225/70/15 tire on the front. Is anyone running this combination on a stock Duster? Will I have any clearance issue in either front or back? For rims, I am planning to get 15x8 with a 4.5" backspace on the rear, and 15x7 with a 3.75 backspace on the front.

When I was looking a couple of years ago I could not find this size, so I ended up with 255/60/15's on back.

I agree too tall. 225/60/15 will be close. Close will vary close depending on alignment, past collision damage and bodywork to fenders. Turn the tire so the edge is closest to the front fender bottom lip. Then back up down a driveway with the tire in that closest position while someone watches for clearance. I really do not think 225/60/15 will work with 3.75 backspace 15x7 rims.. You need to run a 15x7 4.25 to 4.5 backspace rim. You could give 4.0 backspacing a try, but don't get your hopes up unless you want to lip back 1/2" of the bottom front edge of the fender lip. OR see if you could push out the fender with the bottom fender stabilizer bar a bunch (drill new hole in fender).

It's really the back that needs more wheel and tire in the well to fill it out. I just don't want to end up with a huge difference between front and rear tire sizes that won't look right or handle well. That was my only reason for considering upping the front tire size from what I currently have.

Does anyone have experience with a 275 tire on the rear of a Duster. Pictures of these tire/wheel combos on Dusters would be greatly appreciated as well.

I have a set of 15x8 Jeg's Sport Drag rims with 255/60-15 tires,and this combo would work best for a stock rear suspension A body. These back rims have 4-1/2" backspacing. The fronts are the same brand rim, but are 15x7, with 4" back spacing. The largest front tire you can use w/o rubbing or hitting something are 215/70-15's (which is what I'm using after some experimentation). KK Last edited by Kudakidd; 05/11/10 03:00 PM.

I have a set of 275/60 R15 BFG Radial T/As on the back of my '74 Duster. I know they are 15 x 8's but I dont know the back spacing off the top of my head. I have 3" over arched springs though.
