What size tyres on my new 10 x 18"
Hi
I did just buy some 18" Compomotive for my FD.
It is 9 x 18 ET 44 in the front and 10 x 18 ET 44 in the back.
What would the perfect size of tyres be if I do not want to roll the fenders..??
I want them to be as wide as possible. Is 275/35-18 in the back ok..??
Thanks

depending on the tire make and model there are some good combos that work with a nice and short O.D. both front and rear in that 18" size range.
I thought some tires had a 265/35 that was similar in o.d. to the 285/30 but I cant rememeber. a 255/35 might also work well, but it all depends on the tires exact real world measurements, you cant just go by the size callout on the sidewall.

Hmm... I would try the Yokohama A048 but they only makes them in 265/35-18 and 285/30-18 for the rear tyres. Do you think the 285/30-18 would fit to the car without touching the fender..?
In the front they make 245/35-18 so i think that is what i am going to try...

I did some calculating yesterday and came up with this combo:
245/40/18 Diameter = 25.56
275/35/18 Diameter = 25.58
OEM 225/50/16 Diameter = 24.86
These are almost identical to one another in diameter and also very close to the stock size. Your speedometer will read %2.9 lower than your actual speed.

go with the 255 front and 275 rear. thats what im running with no prob and you have better offsets than me. i will put 5mm spacers in the rear and be the same 44 in the back as you but if you check out the pic i posted you have room. mine are 49 in the back. https://www.rx7club.com/showthread.p...29#post7994629

You'll want to go a little shorter than that up front. Tall tires are what rub up front, the wheel wells are small. Go w/ the 255/35

Why would it rub when the circumference is only very slightly larger than stock?
IE the stock (225/50/16) Circ. is 78.09
The 245/40/18 Circ. 80.79
I think I must be missing something...

So now that I understand the numbers better;
a 245/40/18 is 0.70 inches taller than stock tires. I guess that is enough to cause problems?
In comparison, a 255/35/18 is only 0.17 inches taller than stock.
The 275/30 are even taller than the 245/40, but it doesn't matter as much in the rear.
