One of the guys at lethal runs 275/305 with no issues.

There are a whole lot of car maufactors who don't follow that logic.....Corvette, Porsche, Lambo, Camaro, Mustang and many more.

By that it means to evaluate a given manufacturer's production sizes identifying tire section width, aspect ratio and wheel diameter... for any given tire application I'm considering just one of the things I do is to know the ranges of sizes available if I am going to use staggered sizes on any vehicle I run. I might in this example run a 315/30ZR19 on the rear and a 305/30ZR19 fronts...this example in the Michelin Pilot 4S is one size differential.

Many times you'll find limitations in consecutive sizing ranges and It's because of OEM manufactured reasons and/or supply and demand for certain types of tires.

So it's all about minimizing the variance in tire dimensions between front and rear tires assuming the same product set of a given manufacturer's. This reduces problems with overall handling problems and keeps the overall tire dimensions within a range that doesn't compromise safety.

A good exception in tire size differential is what you see on a top fuel dragster. But then that's an entirely different application of course!

I run Michelin PS4S 315/30/20 on a 20x11 wheel on the rear and Michelin PS4S 275/35/20 on a 20x9 wheel on the front. The sidewalls are very square on both and overall diameters are nearly identical at 27.6" and 27.5". All things being equal, I prefer a square setup, but wanted to take advantage of the extra space out back. I just had never heard that one size difference between front and rear was preferred.

Now that you point out this fact there's no question that particular to the use of low profile series tires in the 20" and higher wheel sizes you are certainly correct. Thanks for enlightening me. Manufacturers have almost no limits in dialing in performance.

I run 315/30/20 on 20x11 P6GR TENs on rear. And 285/35/20 on 20x10 up front. Wrapped in MPS4S-ZP for summer. I have another same wheel setup except MPS4AS-ZP for winter setup. Car is lowered 1” all around on magnaride. No issues.

On top of the choice of the tire...which i won't comment..
Are u putting a 305 on what rim?

I run square. Matches my personality.

I installed a Roush Phase 2 supercharger in November and when the weather gets better I'm going to run Nitto 555r2 305/35 /19 tires on the rear. My car is a PP and my question is should I run the 245's on the front or the 275's?I'm more interested in function over looks. Does either way make a difference? Thanks in advance for your help.

If you're going fast enough to need 305s in the back, you may eventually want to stop. 275s for the front would be a better idea than 245s for stopping.
