I have a stock 98 z24 and found rims and tires for a great price. Will a 235/45/17 tire on a 17x7.5 rim with a 40 offset. With they rub? If so where and what size spacers do you think ill need to correct it. Any input will help guys. Thanks!
it depends on what spring/strut u run. I have gravana coilovers right now and run a 235/40/17 with plans to upgrade to the 45 series soom. my wheels are 40 mm offset aswell.
Everything is stock on my car.
I was wondering this also, I'm on megan racing springs and koni yellows I wonder if it'll fit, sorry to threadjack but wat is the width difference between the 235 and 225?
Yea I know but I wanted to know how much wider as in inches so I could see if it is actually worth getting the 235 I don't wanna pay more money for a tire that's only a quarter or maybe half an inch wider and have it rubbing my fenders
the first number is the thread width in millimeters. 235 is 10mm wider then a 225
It never ceases to amaze me how little people know about tire sizes. It's not rocket science.

205/55 R16.., what does this mean? Most people understand that the last number is the rim size in inches and the first number is the tread width in millimeters. But, what about the middle, number 55? Well, it is the aspect ratio, which indicates how tall the sidewall is. To find your sidewall height take the tread width and multiply it by this percentage and you get your sidewall height in mm. Percentages, metric and standard units of measurement, oh, the fun we are going to have here.
Now that you understand a few things about tire sizing. What can be done? Well, oodles really, including how many revolutions it makes in a mile (revs/mile), which can be used to calculate speed (revs/mile/time). To figure revolutions per mile we need to calculate only one thing, the overall tire height, which can be found by using the given information on the tire about its size. What gives a tire its overall tire height? Rim size and sidewall, of course. With the tire listed above we have a 16 in rim and a sidewall that is 112.75 mm tall (205 * 55% ), but beings that the sidewall is at the top and bottom, multiplying that number by two gives, 225.5 mm of total sidewall height. To convert 225.5 mm to inches divide by the conversion 25.4 mm/in, which gives 8.88 in of total sidewall height. Accordingly, 16" + 8.88" = 24.88" of overall tire height.
So...
Rim size in inches + ((Tread width * aspect ratio * 2) / 25.4 mm/in) = Tire Height in inches
How are revolutions per mile calculated from overall tire height? Well if you remember from Geometry that the circumference of a circle is equal to the diameter (tire height) * pi, or 24.88" of overall tire height * pi = 78.16 in of circumference.
Now, one circumference is one revolution, so divide the circumference one mile...
63,360 inches per mile (conversion factor) / 78.16 in = 810.6 revolutions per mile
To find your revolutions per mile in one simple step, use the following combination of the above formulas.
63,360 (in per mile) /(((Tread Width (mm) * Aspect Ratio * 2)/25.4) + Rim Size * pi) = Revolutions per mile
Now you know.
basically, if you are not running coilovers, i am pretty sure that you will rub with a tire any wider then 225/45. I could be wrong, as i run 235/40s right now with my gravanas, and plan to run a 245 and i MIGHT still rub.
^^^^ Keep in mind the big brakes typically act as small wheel spacers, I know on mine (especially on the rears) it pushed the wheels out a bit so that will give you more strut to tire clearance then most.
Okay so wat bout running some small spacers? I know on my friends srt4 they solved the rubbing issue with some spacers all around? Plus I wouldn't mind the wheel to stick out a bit farther especially since the wheels I want have an offset of like 42

let me correct this...i plan to run a 235/
45 and i dont think i will rub
