Well on the rear if you have the right backspace a 275/60/15 would be nice and i don't know how a 235/60/15 would do on 10" rims on front, but that's an idea, i was gonna do that set up on mine but have 8" on the front, just did'nt want to spend the money for new rims and tires and plus mine looked good anyway, maybe this has helped you

im mostly looking for the width number. will 275's be the right size for the width? i think the tires currently on my truck are a little tall. they dont have a standard number i think they just say 31's on them there firestone firehawks.

i'm running 255/70/15 and they are 29" tall the 275"s are i think about 28 1/2 " tall that's with a 8" rim so they will be shorter with the 10"rim. the sizes i'm quoting are according to a bf goodrich size chart

When looking for the width of these metrically designated tires just divide the millimeters by 25.4 and you will have the distance in inches. 275 divided by 25.4= 10.827, which is a little over 10 3/4". The aspect ratio is a percentage of the width. A 60 series tire has a sidewall which is 60% of the width of the tire. Tire diameter can be figured out from this by multiplying the aspect ratio by the width, doubling it,and adding the rim size. Some cell phones have conversion calculators nowadays that make all this easy. Some tire manufacturers may fudge a little on their true widths and sidewall aspect ratios. I'm not trying to sound like some brainiac, just trying to be helpful.

I got 275/60/15 on a set of 15x10's all the way around. My drop is 5/7 drop and yes, the tires do rub on the front some... You can't turn the wheel all the way and on bumpy roads, they hit the fenders. These are just temporary, I wouldn't run them on the front if you dont have to. The back are fine, no problems...
