so ive picked my wheel and tire setup, but i would like to kno whats the widest tire i can fit on my FRONT wheels for this setup....

im getting axis hiros in 18's and i dont kno how wide of a wheel they sell it in 18s. i am also getting Falken Azenis RT 615s on these wheels but dont kno how wide i can fit on all four corners.

i want the same width wheel and tire combo on all four corners, as wide as possible. does anyone kno how wide of a tire u can squeeze into the front wheel wells? i kno the rear can fit a decently wide amount of tire, but i am unsure about the fronts, i kno it involves rim width as well, but i dont kno the widths of the 18s on hiros. i only kno of 8.5 and that will fit 245s for sure, but i am looking into as wide as possible........ any thoughts????????

I heard if you have wide enough wheels with the correct offset the car will accomodate 275's all around. If your wheels are 8.5 inch wide i would not go wider than 255-265.

Are you going for looks or handling if you don mind me asking?

for handling. i want the most grip humanly possible.

Going too wide
1. Makes handling in the wet bad
2. Might make the car difficult to turn
3. Tramlining

I would go for a compromise with 255/40/18, improved handling overall.

255/40/18

all very good points, i read from the staggered wheel sticky about the wide tire=bad in wet convo.

im pretty sure 255s would fit on 18x8.5

is a 40 profile acceptable?
like will the overall diameter be close to original with that? or would 35s be in order?


edit, ps, whats tramlining?!!!!!!!

Tramlining is kinda like when your tires a easily move towards a direction you didn't originally intend to because of natural conditions of the road causing you to always correct your steering.

40 profile is fine. Nice choice of tire/wheels!

thanks bro! im doin axis hiro bc of the caliper clearance, i am going road coursing in the near future and have BIG plans for my BRAKE UPGRADE....

18x8.5 axis hiro hypersilver.....thats it, decision made

ps, just read ur sig, makes sense now, send me a pic!!!!!

255/40/18 is the closest you can get to stock tire circumference with 18"

Hi Roxanne, here is a pic before the new tires: http://www.rx8club.com/showthread.php?t=77493

I don't have any new pics, as I haven't really driven the car much during the last few months due to various reasons. Hopefully I'll have a few new ones in a week.

think you could get away with 265/35/19's up front?

I'm pretty sure you can if the offsets are right...the knight sports rx8 runs 19x9 Advan RS's on all 4 corners, and that's alot of wheel to only cover with 255mm of rubber.

Its really hard to say how much rubber you can fit, without knowing your rims with... nonetheless if the rim is wide enough to support it, i dont see any issue of going 275 on all 4 corners. Theres a lot of people on here who have that size in 18" rims.

If you are going 275, i would recommend taking a 35 profile
If you are going 255, i would recommend taking a 40 profile

Wow. 18x10 On All Four With 285 35s. Wow!!!!!!!!!!!!!!!!!


I Want That!!!!!!!!!!

Just go to www.1010tires.com, use the tire calculator to try all the different combinations that you want, very handly to compare with original size.

Thats crazy. I wouldn't mind running 275s all around, but 285...wow.

i went there and ran thru 6-7 diff tire sizes from 245 40 all the way to 295 35. the most logical answer is 255 40 18 and they require a rim diameter of 8.5-10 inches wide. i KNOW axis sells the hiros in 18x8.5 so im good. if they sell a wider wheel than that (18x9, 9.5, or 10) then i will ge tthose.

otherwise, there we are

thanks for all your input. !

sweet post pics when you're done :)

Is there 600+HP in these cars with 265-285+ wide rubber? ... or are they running the standard 237 HP (or less) which can barely snap the stock 225 tires loose in first gear?

Sounds to me like someone is trying to make up for their tiny dick!

Sounds to me like someone is trying to make up for their tiny dick!my first instinct was to say that you're the one making up for shortcomings between your legs, but I changed my mind and realized you're trying to compensate for your shortcomings of brain cells

maybe if you had any idea how a car (#) moves in any direction but forward you'd have a valid point, but clearly you do not

"grip"


look it up moron

Dee Dee Dee....

I hope you meant 255/35-18 :Eyecrazy: but it's by no means the widest like you asked

35 profile? i used the tire calculator and they suggested 40 profile. whats ur thinking behind goin to 35? do u think they will be rotating too slowly with 40's?

get 18x10 with 42 offset and roll the fenders front and rear
then put on 295 30 18 all around

thats about how wide you can do...with some moding of the car..and you might have to eliminate the fender liner in the front.

i have 285 30 18 advan A048 on mine. unfortunately i only have a 9.5 wide rim so thats why im stuck with 285.


-gene-

30 profile is just too much for me. or should i say, not enuff. i live 10 mins outta philadelphia and i commute to work TO philadel[hia and i cant ride on 30s on those garbage things pennsylvania calls "roads". 40 is my personal limit but will budge to 35 if need be. is 255 40 on 18x8.5 reasonable? or is a 35 profile suggested?

You have the right size in mind. 255/40/18 on 18x8.5.

i thought so, falken doesnt make the 615s in 35 on 255's anyway. im set.
