View Full Version : Can you help me pick a wheel?
05-08-2006, 01:27 PM
North Carolina wheeling is mostly trail riding with a lot of big slick rocks. Wheels that stick out past the side of your truck go a long way to prevent body damage. I currently run 255/85/16 BFG MTs on stock wheels.
Does anybody know how much backspacing I'd need to stick out past the side of the truck? Does anybody have a particular brand/model of wheel that will do the trick?
Thanks in advance

I have a set of Trail-Gear 1.5" wheel spacers all the way around. They put the wheels out past the fender flares pretty good. As for a rim I found out that if you get a 16x8 with a 4" backspacing that would equal what I have. Just be ready to trim some plastic with this tall of tire, with that much offset. Hope this helps.http://i49.photobucket.com/albums/f294/OldSven/p4300007.jpg

I'd put larger flairs on if you are going to have your tires sticking out, otherwise you'll end up with chipped paint from road debris. You could always go with a wider wheel too- say 8" instead of 7" etc.

I'm a super-big fan of stock tires and backspacing. When the tires start getting wide it may be okay to get some spacers in there, but with your 255s, I'd stick with what you got, that combo is (in my opinion) the best looking.
On another note, also beware that adjusting the centerline/backspacing of your wheel may add undue stress to your wheel bearings

If thats the stock size tire stay with the stock rims.
When you change offset you change a lot of things in the suspension geometry. In particular "Scrub radius".
When a vehicle is designed they design the suspension to ideally have the the front tires pivot in the center of the tread or as close as possible. Once you throw in caster and camber its impossible through the whole turn of the wheel but close.
If you lay under your truck look at the ball joints (the point the front knuckle pivots on). If you were to draw a line though the ball joints axis down to the ground ideally where that line hit the ground would be the center of the tire tread.
What being near the center of the tread does for you is makes it easier to steer. If you offset the wheel then you are adding stress. The point that line hits the ground is now inside the centerline of the tire. so as you drive down the road the road is trying to force the tires back. You will start having problems cupping tires shakes and more brake pull when you are off center steering such as braking in a turn.
Now think about the extra strength it would take to over come rocks off road.
Now if you are going up in tire size then go a little wider. It will get the line back closer to center of the tread...
With stock size tires you could get away with an 1-1.5 inches without a lot of harm but if you start messing with revers wheels with 2 inches of backspace and the stock size tires...its going to be brutal on the front suspension.
I think most of the stock Toyota IFS wheels are close to 5 inches of back space on a 15x7 rim and 16x7.. Most of the off the shelf one size fits all wheels in a 15x8 16x8 is around 3.75. So if you went up a little in tire size it would work out about right.
The Down side is what was stated in the above post. That offset on an over sized tire might get you into a clearance issue with the fenders.
Go find a ditch and get it flexed out since you have the tires you want to run already on the truck. The tire is going to be roughly 2 inches farther out if you went to a 8 inch rim with a 3.75 offset. Turn the wheel and get an idea if you have that 2 inches and if not what needs to be done to get that 2 inches.
