18x7.5 inch wheels. What size tires to go with?

I have a 2006 accord ex sedan v6. I bought some 18x7.5 wheels and was told 2 different sizes to put on it. one was 215/40/18 the other was 215/45/18. Was told this by 2 different wheel shops. So my question to you is what tires do I put on it? I am planning on dropping the car maybe 2-4 inches as well. 2 if possible dont know if I have room to drop it 4 inches. Please help. Looking to buy tires asap.

Thanks

I'd put 225 45 18's. 45's should be good, you want to give it a bit of a cushion.

Agreed. I've ran 225/45/18 for my winter set-up on two separate occasions. They will work well on 7.5" wheels. I had them on an 8" wide wheel with little issue but they get too stretched on anything wider.

You can also run a 235/40/18 but 215/40/18 is a bit undersized for our cars.

Also, you failed to mention the offset but guessing since it's a 7.5" wheel you will be somewhere around 38-45mm. You'll be fine with that drop.

225/40/18
225 45 18
235/40/18

Could choose any of the three. I was slammed with 18x7.5 wheels with a 44 offset and added a 5 mm spacer. I went with 225/40/18 front and 235/40/18 in the rear. Looked nice

I gave ran 225/45/18 and 225/40/18 on same size tires. The larger diameter is closer to stock size if you had 16's stock. Keep in mind if you are dropped they will have a bigger chance of rubbing. 215/45/R18 is the size I will be using next time

I have the v6 6 speed so stock they are 17s. Ya I dont want to rub and I want to keep my speedometer on. So I was thinking the 215 width as well but just need to figure the height to make the speedometer correct.

If you are worried about your speedo, use this...

Tire Size Calculator - tire & wheel plus sizing

but to be honest, I've ran as much as 3.5% oversize and the speedo difference is negligible.

I an on my original 16 X 6" Honda rims; stock tire size is 205-60-16. I am running 205 65 16's. it is off by maybe -+2 at 70 according to my GPS, I have not checked recently so I cannot tell if it is + or -. There will be minimal differences in speed but as you drive faster than 70, the difference will be larger.

235/40-18 is a perfect fit for the wheel and the ratio

Ok anytime anyone has a question like this you can easily find this question out yourself by going to tirerack.com, putting in your vehicle year make and model, then choose to look for wheels, then check whatever size wheel you have, and then magically they put what size tire you need! 18 inch wheels needs a 215/45/18 and a 19 inch wheel needs a 225/40/19

yes it does but sometimes the width they list might rub. which is one reason i asked the question. 225 is wider than 215 and I was told by actually 3 different tire companies to use 3 different sizes. lol

I can't imagine you would rub with a 225..

You still haven't listed the offset so any speculation if the tires will rub, are, at this point....speculations.

Now has anyone heard of or used FEDERAL SS-595? I have found some good reviews on them. None bad. Only thing is they say the size that they list them under is not correct. They run wider than what the tire says. You can check them out at this link. I am just looking to see if anyone else has any input on these tires.

With only a 2 " drop as u stated in your first post you won't rub with any tire size. I had 18x7.5 with a 37 offset an i had 225/40 in the front and 235/40 in the rear. Slammed all the way down on Tein SS and never rubbed. You will be fine.

Might rub the liner if 4" in front over big bumps. Should be OK. Tuck the liner if anything (this is only an issue if 225/45/18)

Federal are Taiwanese/Chinese tires. I would probably pick them up used for cheap but probably wouldn't spend the cash to buy them new.
