how much rubber can I use?

[PappyJoe]

Looking at ordering wheels and trying to figure out size. I'm doing resto mod so going bigger and wider. Would like to know what size folks on here are using and if modification was needed what they had to do to make them work. Appreciate any and all info. Thanks in advance.

Guess it would be helpful to say I'm doing a 1971 Satellite. Sorry. Thanks

You wanting it to look like an oversized Hot Wheel or just going from 14" to 15"?

 

[PappyJoe]

Lol! Guess oversized hot wheel. At least 17s but considering 18s.

18" rear 16 front 73 SSP

My '71 Road Runner had 16X8 with 4.125 back space & 255/50 tires on the front and 17X9.5 with 5.25 back space 295/45 on the rear, no rubbing or fender lip rolling.

Thanks! That's the info I'm looking for!

!8 X 8 in the front 19X 10 out back, tires are 285's with plenty of room (I'll use 295's next time around). No modifications other than lowering it roughly 2".

I also found another reference showing 285/40-20 10 inch with 5.25 BS on the rear and 245/35-18 8.5 inch with 5.25 BS on the front.

Seems I should be able to run the sizes I want to with 18s on the front and 19s on the back as long as I keep to that 5.25 back space.

I think I'm going to invest in a wheel fitment tool just to make sure.

Not sure about the 71s but mine is zero offset. lf your refering to 9.5 wide with 5.25-5.5 BS then that's pretty standard for cast wheels and will just leave your wheel a little tucked in on the ourside.

Makes sense. Thanks. Zero offset and you obviously don't have any trouble with the leaf springs in the back. That's one of my concerns. The other is on the front turning. Seems really close with the stock 14s on there turning to the outside.

I went ahead and ordered a wheel fitment tool just to make sure and have peace of mind when I order the wheels/tires. Planning on using the black torque thrust with polished rims and some BFG KDWs. Just want to fill out those wheel wells as best I can.

Just remember when figuring backspace that the advertised wheel width is measured inner bead flange to inner bead flange, backspace is calculated from bolt pad to outer wheel lip so you have to add about an inch to advertised width before figuring backspace. Offset is the positive or negative difference of the distance from the back of the bolt pad to outer lip of the wheel, either to the front or back of the wheel. When a wheel has has less distance from the bolt pad to the rear than from the bolt pad to the front, that is negative offset and vice versa. Example:

17" X 9.5" is actually 10.5 overall width. This divided by two equals 5.25" or zero offset.


Good luck wheel shopping!

5.5 BS on 20x10 Rims in the rear

18x8 with 5.5 BS up front

Thought I would update on the choice I made for wheels. These are 20s with 295s on the rear, 18s on the front. I came out needing a small spacer to clear the leaf springs but I'm happy with the outcome. I did get the measuring tool and still managed to get the back spacing wrong but not too bad.

Stance will be different with full weight of gas tank, drive train, etc. Coming along. Again, thanks for all the information.

What is your sidewall ratio for the tires?

Glad you are happy.

That looks sharp!
Here is my similar setup, and how it sits with 275 and 245 rubber, both spaced out about 1" w/hubcentric spacers:



One cheat I had to do was cut the front fender support that runs over the top of the tire. Partly the size of the tire and because it sits lower, it was hitting the top of the tire when hitting bumps. For now I cut it on the fender end and pushed it up out of the way, but one of these days I am going to have a shop weld in a 2-3" extension for it and reconnect it to the fender, but I really dont think that skinny little support bar provides much anyways.

Had to tell you she looks awesome! Hope mine comes out anywhere close to that good!
