Default Quick question about tire size for VIP look

Guys I need a quick answer to this question please. My new wheels arrive tomorrow and I need to secure some tires. What tire size do I need to go with to fit these wheel specs. Now I don't want an unsafe or over stretched tire just a nice stretch and ideal for fitment.

Wheel specs:
Front 20x9 -1
Rear 20x11 +12

Thanks

Here is the the setup I'm running on my 20x9 and 20x10.5
Front: 225/35ZR20
Rear: 255/30ZR20

With this setup you will have same tire height front and rear and equal stretch with out too much stretch.

I would not go for geeznuts setup unless you want a taller rear tire. Not to mention the rear tire size is oversized

Sorry to thread jack but anyone ever run a higher profile in the rear? For example, 225/35 front and 245/40 rear? Does it have any affect on the ride?

You can go with a 225/30 but the size wall is SUPER small and the load capacity is much lower making it easier to blow the sidewall. the factory 16" is 205/60R16 which is 26.16" overall diameter and a 225/35R20 is 26.2 overall diameter so its the same.

Just because the side profile is 35 front and rear does not mean the sidewall height is the same. Take for example 225/45R17 and 255/40R17 have the exact sidewall thinkness where as 255/45R17 would be 1" taller in height and would look way off.

If you are going to buy new tires make sure the tire overall diameter is between 25.3-26.3. If you are not sure what is the overall diameter is, here is a link to the company I work for

Here is my setup with 225/35ZR20 front and 255/30ZR20 rear Falken FK-452

That would be rediculous First of all 245/40R20 is closer to a crossover/SUV size and is almost 28" in height. It would rub all over the place and not to mention look stupid.

225/35/20 and 245/35/20. Id rather have a slightly bigger sidewall to prevent bends and have a little bit more comfortable ride, rather than driving on rubber bands

If it's strictly a show car I would do 225/30/20 and 245 or 255/30/20. Sounds like you need all the help you can get to fit those offsets.

Ok time for some education here. If I had to guess or go at this alone I would have chosen these tire specs. Why is this NOT good for the fitment I need.

Front 245/35/20
Rear 275/35/20
