Think there will be any issues with putting 20x10's all around wrapped in 275/40ZR20's? Not looking to mess with lowering, cutting or spacers. Set it and forget it. Hope to hear your thoughts~

Yes, and read all about it at Tire Rack........

I all depends on the wheel offset.

Well, the stock 275 wheels are 20x9.5 with +18.5mm offset so just need to figure out what offset you will need to keep the inside of the wheel at the same position while going to a 20x10. The online calculators should tell you this.

I have 9.5" up front with +15 offset with 275/40/20. I have a feeling you'll have issues with a 10" wheel with a similar offset. It may work if you push it out a bit but would look goofy.

I like this calculator. It gives a visual representation of the numbers.

Wheel Offset Calculator

Use our wheel offset calculator to visualize the new tire position when changing wheel and tire sizes. Convert wheel offset and backspacing to calculate the correct setup for your vehicle.

The problem with a low offset on the front is that you can and most likely rub on the outside, either the fender or the liner.

I had a set that were +8mm when installed with the spacers to clear the suspension, but rubbed the finder liner on the outside. Just something else to consider.

I'm looking on Tire Rack atm. I dont see where you can add non-standard wheel sizes to the calculations to determine proper fit. Then again im a newb

Is that 8mm enough to change the steering geometry? I don't know how much a 1/4 will move things, but the farther out you go from the hub the more it affects your steering geometry and camber angle.

I have not seen this posted here so thought I would share. I found a neat wheel calculator to play with. Just plug in your original or current wheel width and offset, then plug in your proposed new wheel specs and see below how the inner clearance and outer wheel position will change. Using...

It doesn't change suspension geometry. I've been doing alignments and tires for a loooong time and racing in some form or another just as long. On a daily driven car, you'll never notice the difference in "scrub radius" changes.

The set I had to space out, I went 1/2" out because of the spoke design to clear my Brembos. I also had to use longer studs to do that. A 275/40 rubbed the fender liner on the outside. Not bad, but it ground off a couple of the push pins that hold the liner in. Swapped to 245/45's and it cleared fine. Neither of which changed my alignment.

One thing about spacers on our cars... with MOST wheels, 6mm spacer is as thick as you can safely go with the factory studs. Any thicker and you'll need longer studs.

When you mount a wheel on our cars, if you can't get 7 full turns on the nut before torquing it, there aren't enough threads engaged to be safe.

These are pics from where I was fitting that set of wheels and was testing stud length and thread engagement.

These were the wheels on the car

I kept them about 4 months and took them off to put my Centerlines on

DAMN! You do quality work my friend.

There's a lot of places I cut corners and a lot of things where safety isn't a concern. Keeping my wheels (or anyone else's) on the car is NOT one of them lol
