I have bought 18" rims to possibly to go on an 09 TSX. They are 8" wide.

They are off an 08 Accord V6 coupe:

I was thinking of mounting 245/40R18 or 225/45R18 Bridgestone Potenza RE960AS Pole Position tires. Opinions on the wider tires on these rims. Will they fit well on the rims? Will they fit in wheel wells?

Thanks in Advance.

Any help would be appreciated.

I say neither.

225 is not wide enough.
245 is too wide.

you have an 8 inch rim.
therefore you should be using 235 tires.

oh, and for the next question:
235/40

tire brand is your choice.

Thanks for your feedback.

The only thing that would worry about the 235/40 R18 is that the diameter is 645mm compared to 657mm of the 225/50 R17 that comes on the 09 TSX. That is a difference of 12mm.

A 235/45 R18 has a diameter of 669mm, which is 12mm off in the other direction.

The 245/40 R18 has a diameter of 653mm which is only off my 4mm.

Tirerack says that 8" is the bottom of the range for these tires, but I am leary.

I don't have a TSX, but my 03 maxima has a 225/50/17 stock wheel size also and i'm running 245/40/18 on 18x8 wheels w/o a problem (and I think it rides nicer and is closer to stock size).

I think one problem here is that this is the First Gen TSX part of the forum...so I think we all assumed that you were looking for tires to fit a 1st Gen TSX, in which case the 235/40 recommendation was spot on for a replacement of 215/50-17's.
For the 2nd Gen TSX, you are, indeed, correct in stating that the stock size is 225...so, yes, the 245/40 is closer to the stock rolling circumference...

Os.

Thanks, your right of course about the forum. But there isn't a sub forum for wheels and tires for an 09 yet and I need the experience of folks like you. So thank you for your reply.

So far I have had mixed responces on a 245/40 fitting on an 8" wide wheel. Any other opinions on this?

245/40 will fit, depending on the tire. Some tires are wider than others, regardless of the treadwidth. Check the actual width of the tire before you make a final decision, but a 235 fits with room to spare so I imagine that a 245 should fit without much complication.

I would give a to that tire/rim combo. I ran a 235/45 on a 7" rim on my '03 Jetta GLI with no problems so you would be fine to do what you want.
