245 is waaaaayyyyy too wide for a 7.5" wide rim. thats more like dodge viper territory. anyways, you would want something like 215/40/18, 215/45/18, or 225/40/18. check out the wheel and tire forum stickies, theres a tire size calculator there so that you will get the closest to stock diameter and circumference.

The bead will still seat proply on a 7.5" in rim, Im just woried about rubbin.
the tire is not the right size for those rims. even on an 8" wide rim, 245 is too wide. and yes, you will most likely rub with 245's. simple as that.

I agree. 245 is wayyyyy to wide. If you want to slow your car down and lose like 4mpg, go for it. Other wise go with a 215 or 225 like others have said. I think 225 is like an 8" wide tire.

245 is not even close to beeing too wide for a 7.5"

245 is NOT viper territory

i have 245/40-17's on 17x8 rims and the sidewall is almost straight.
the edge of the rim actually sticks out about 2mm more than the tires do.
so on a 7.5" wide rim those tires will be perfectly straight with the rim.
it also depends on the tire brand/model but you get the idea.

Accord_boy619..what you have to worry about is those wide tires coming in contact with your suspension. the rims will clear it, but i dont know if the tires will.

Clearance from the fenderwell n suspension pieces were my only concerns. I work part time @ SEARS Auto thats why I know that 245/40/18 will fit on 7.5s

ok-if you say so-then go for it, but in my honest opinion, you are making a mistake. like i said, check out the wheel/tire forum and do some research there.

those types of sites are too general and misleading.

you have to take into account the sidewall height as well.

For example, a 245/45/16 tire can fit a 7.5 in rim, or even a 7 in rim as some have managed, but a 245/40/16 tire will have a hard time getting onto something that narrow

just go to the tire manufacturer's website and check out their specs.

there you go.

BTW-do some math and figure this out, c'mone, think logically here.

245 mm wide = 24.5 cm wide.

2.54cm/inch

24.5 cm / 2.54 = 9.65" wide. and you wanna put that on a 7.5" wide rim. ok. maybe an 8.5" wide rim would be ok, even 8" is really stretching it. sure, you may get the bead to sit, but its simply not the right size tire for that rim.

I guess my whole engineering degree goes to shit here.

I sayin it fits cuz I tried at work, Yea the tire was a bitch to put on. Hell it took 3 people n 4 forks but it went on.
first of all, like i said, maybe you got it to fit, but its the wrong width for that rim, secondly, 18" rims are heavy as could be and add to un-needed unsprung weight, Thridly, if you do some research you will find the answer that you are looking for, which I have been trying to tell you in this thread. But hey, ultimately it is your car, so do what you wish.

Say man, I remember you from back in tha day. Nice to see your accord finally. If you don't remember me, i was deployed the same time you were in 02/03. Anyways, 5thgen guys can't put have of the size of wheels and tires we can. My 19x8 wheels with 235/35 tires won't fit on my boys 5thgen but they fit fine with a little rubbing on mine. 245 is way too wide for a 6thgen if it is lowered. if it is not dropped, you won't have any trouble. the ideal size for a 6thgen is 225. my 235's rub too much when i first put them on, so i had to raise the car an inch. i wish i still had my 235's, but try them if you want then you can make the decision as to how they ride/rub.

4cylinder 6th gen: (~25" dia. wheel OE)

Proper tires for upsized rims:

17" rims 225-45-17 (7"w ideal)
18" rims 225-40-18 (7"w ideal)

This will maintain near stock diameters and fit.

6cyliner 6th gen: (~25.5" dia. wheel OE)

17" rims 215-50-17 (7"w ideal) *TSX/Acura/AV6 7th gen Accord common tire
17" rims 235-45-17 (7.5"w ideal) *also TSX A-spec tire
18" rims 235-40-18 (7.5"w ideal)

225-45-17 and 225-40-18 are very common OEM tire sizes now, and thus likely offer the largest choice and price value of the above listed tires.

In addition it's important that you have a proper rim offset. +55 is often stock on most Honda's: +48 to +50mm is an ideal aftermarket rim. I would advise not running a rim with an offset great then +42 at the most, though +45mm would be better to prevent rubbing.


Just my 2-cents.

I have yet to see a 7inch wide rims in 18inch diameter
