Tire question

[FUN2RIDEFAST]

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.

I tend to prefer one size differential between front and rear if you stagger. Two size differential tend not to be a good thing unless you're running a street rod or something like that. My opinion.

What is "one size differential" and "two size differential"?

Thanks for the info.

I was running 285s up front and 305 G2s and this year since I bought more rims, I'll be running 275s in front and 305s riis in the rear. To me, the 285s looked too big in the front.

Sounds like a plan. I'm going to do the same. Thanks for the information.

I run 275/35 fronts and 305/35 rears on both sets of wheels.

Thanks. That's exactly what I'm going to do. Any notable difference in handling from stock?

On the PP wheels? I wouldn't go any bigger than 285 on the 9.5 inch rear PP wheels. Get a set with 11 inch rear wheels if you want the benefit of the wider tires.

I drove it home on stock and changed them out as soon as I pulled into the garage. Also, mine are 20s I am sure they ride just a tad bit stiffer than stock.

What wheels?

I've got a PP car. I'll put the rears on the front and I already have a pair of eleven inch rims for the Nitto's. Thanks for the reply.

What is "one size differential" and "two size differential"?

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 had 285 on the front and would tramline everywhere. swapped to 275 this time and much better. and i think they look better too.
