245/40 on 18x9.5?

ctfo1885 · 06-19-2015, 10:34 AM

I thought this was a common tire size without too much stretch. But I have a buddy that has been having issues getting someone to mount his tires on his new wheels. Anyone else have this issue or know of a tire shop that wont refuse to install 245 on 9.5 wheels?

I have that same size on my 18x9.5 and never had any issues having them put on. I just went to a local mechanics shop in my area cost me $80 mounted and balanced

Might be not the tire being a bit stretched for the wheel, but the shop probably has an el-cheapo mounting machine with a hard metal/plastic lever.

They might have just refused based on how expensive the wheels looked, and didnt want to be liable for chipped paint.

this was the reason for one of the shops that declined him

That's a little stretched, but really not that aggressive of a fitment. Most generic tire shops won't do things like that due to liability reasons, to the point where I've even been told they wouldn't adjust my rear camber during an alignment because the control arms were aftermarket. Might be worth a trip to one of the many well-reputed tuning shops in the area that can do it.

That is a common tire size and is not much of a stretch. We'd be happy to mount them up.

I have the Dunlop ZII in that size. Took my car to Merchants Tire as they were able to mount on painted rims without damaging the rim.

Of course, not all tires are the exact same size. Even though the rubber says 245/40/R18, the actual dimensions will vary by brand and model.

I'm such a black sheep. I like my sidewall flush with my wheel. I'm a 255 on a 8.5 myself. I'm sure the stretch crowd looks at me funny....

Any "reputable" shop should be able to do it though. Hell, simple little Mr. Tire by my house would do it, heh.

^^^ your not alone! I felt like I had to much stretch on my 18x11 with a 295. Meaty stance is the way to go.

To add to the topic a 245 isn't a drastic stretch on a 9.5. Any reputable place should be able to do it.

I know this is an old thread, but.

According to Dunlop a 245/40-18 is okay on a 9.5" wheel, it is the far end, but okay they list 8 to 9.5.

I am thinking of doing that I have a friend running that set up and it doesn't look too stretched.
