rim and tire sizes?
 

im looking into running a bigger rim and tire combination. with out bodying a suspension lift or body lift. im just wondering what tire size would keep the same or lil bigger size compared to stock.. i wanna run a 16-18 rim.
thanks

:icon_google:

or search...

i think 265/65r17 is close to the same size off memory... maybe

sorry Curtis. not. even. close! :icon_doh:

that tire size is just over 30.5" tall, knocking out your speedo 8.6%. never mind barely being able to fit in the wheel well.


the largest tire you can run on stock suspension/no BL is either.......
245/70/R16 (29.50" diameter),
245/65/R17 (29.53" diameter),
245/60/R18 (29.57" diameter).


i know this will work since i have a set of 17's with that size of tire on them for my '98, which is currently stock suspension, and these fit. just.

they drive & turn alright, but the rear edge of the inner fender well does rub-slightly- when turning into driveways. not too bad if you go slowly, but for the couple of days i ran them last Summer, i found it to be quite a PITA. plus i didn't want to risk beating the fenders up.

here's a pic to give you an idea of what kind of space you have,

hope that helped you out brother.

***edit*** i forgot to mention that these tires are roughly only 30 to 35% tread, so they're a little under the 29.5" diameter.

bah i was close for memory :icon_urinal:

ok so i just got a set of 18s, the tires right now on them are 235/40/18, im just wondering which tire would a 30" diameter, i wanna run a bigger width than 235, prob 255-265. just wondering what the profile would be to get me to the 30" diameter
thanks guy

Let me see if this link works. This is what I use to figure out overall sizes of metric tires. http://www.rimsntires.com/rt_specs.jsp

Awesome link! Thanks for posting that

walker, 255/55/18 is pretty close. here's another link for comparing tire sizes http://www.miata.net/garage/tirecalc.html

actually.........that tire is just over 29" diameter.

a 255/60/R18 will net you a 30" tire. and it'll knock out your speedo 6.96%


@ Matt: i found that Miata calculator you linked to, to be kind-of a PITA to use. it seemed to take forever to load. but that could just be my dino of a desktop. :icon_shrug:


personally, i've always used 1010tires calcualtor.
