My 71-B-body has mini tubs and 15x10 wheels in the back. Havent picked out the drag radials yet, but I will be getting as big of tire as I can get.

The car is mostly a street car so Im wondering how wide of a front tire I should get? Im waiting to buy the front wheels until I pick a tire size, but I will be getting 15" dia.

If it makes a difference, I installed C-body tie rod ends which are a little heavier duty.

Once you know what diameter your rear will be you can determine what height you want on the front.For street driving I would run a 5" or 6" wide front with some 70 series rubber.Anything less than that and you will be slowing down to take a lot of turns.

I am using a 215/75-15 on 6" wide Torque Thrust's up front on my 63 and I just use a 30 x 9 tire in the rear. I was going to buy the 4" TT but my buddy said since mine is a 99% street car I should go with the 6" wheel and not use the skinny drag tires up front. I am glad I listened to him as the car handles nice with the 6" wheels up front and it is a radial tire I use up front since I use a radial type tire in the rear. Ron

I ran a 205/75 on the 70 Charger. That was w/ a 3.5" rim. If you have a 15x6 you should try a 215/75/15. That is about the same height as a 275/60/15.

I run 225 and 235 70 series on 6 and 7 inch rims on 68-69 B-bodies with fat boys on the back. I have 215/70/15s on my AAR on the 7 inch rims with 275s on the back. In the end as long as they are large enough to drive well it boils down to the stance you like. I prefer a super stock look so I am gonna have mine up at all 4 corners, the exception being the AAR. I fi were ordering front rims for something like your set up they would be 7 inchand I would definitely be running a 70 series tire, the size would end up being relative to the heigth of my rears and then dictated by the clearance limitations.

I have little 185 front runners & 315 M/T Drag Radials out back on my Challenger.

They look silly when the wheel/tire combo is too skinny on a big car. Personally I like at least a 5" wheel but the wider the better for handling.

But your's is a pro-street look (in my opinon) and that is the look you are going for (I figure). It looks great in that form but intended or designed for regular driving including cornering at any amount of speed.

When we mini-tubbed the wells, moved the springs into the frame, we centered a 15x10 Chrysler police wheel in the wheel well then narrowed the rear end length to place the wheels into that center position.

The 15x10 wheels have a 5.5" backspace which gives them a nice 4.5" depth which I like and would like to keep a depth of something close to that up front.

Problem is, the 15x7 and 15x6 police wheels both only have about a 2.5" depth, and the 15x8 has the best depth at 3.5". (when I say depth I think the correct term is offset)

I agree, for a street car I dont like the look off skinny wheels up front, so my first instinct was to get the 15x8. I thnik that may be too wide though... I wonder if I could get the 15x7's refitted? I have seen a mopar site that offers to take your wheels and give them a custom backspace. If I could get those 15x7's with 3" backspace I think the wheel would better match the depth of the rear wheels.

I tried to run 15 x 8 Cragars with a 3 inch back space on the front of my 69 and even with the front end high clearance was an issue. I haven't tried them on my 71 but I was hoping the front could handle them since it looks much bigger. I think 3-4 inch offset would have been OK but would love to here your results and how you accomplished it. Strangely enough I have a set of Cop wheel including the 15 x 10s slated for my 71 as well, but I am thinking my back space is 5.25, they almost cleared my 69 with stock wheel wells and springs but the tires on it have a 13.5 inch cross section.

I'm running 15x8's w/4.5"bs on the front of my challenger. 235/60x15 they fit well. Tire will just clip the wheelhouse trim at the top on full lock going over a bump like at the base of a driveway, which isn't very often.

The 4.5" bs puts the rim very close to the upper ball joint, but does clear.
