Tire advice

Wanting wider tire for my 18x875 xxr527. Currently have 215/45, pretty stretched:eek:

Thinking 225/45 or 235/45. Advice please.

what's your question?

You sound like you know what you want already

Not sure if 235 is too wide. What would look best?

Tc Davis

You have the wheels, you have the car, it's just a simple measurement

215 means 215mm wide, so 235s, you are looking at 10mm wider tires on each side

Hope this helps. On coilovers so can raise if necessary.

roll the fenders flat to run 225

raise up the car to run 235

Yes on rolling the fenders, but in addition, do you think you can take a few mm off the rims to get more offset? Do you have enough clearance on the inside? You'll have to check, but some rims have enough room to take a few mm off. Your rims are way out there.

You should be able to run 245 on an 8.5 rim, so the 225 or 235 is not the issue.

They are just way out there for my taste, but there are a LOT of people that like that look.

215 on a 8.75" rim.....

:rolleyes:

Good for you for wanting something a little more sane.

why the hell do you want to shave the back side of the wheel

so unsafe

you'll have a much thinner mounting pad

if OP likes flushed wheels so be it, who cares

I had 18x9.5 with 225s, so?

What's wrong with 225's and on a 9.5" wheel? Other than tire manufacturers say that it's not unsafe?

The maximum wheel width recommended for a 225 tire is 8.5" I cannot believe you can find tire shops to even mount tires that stretched.

So how bout 225/45 on 18x875? Sane enough?

There is nothing wrong. Just it's not the norm. Then people all freaked out...

Keep your PSI up/in check, you'll be good.

Plenty of shops will mount 225 on 9.5 wheel

If there is enough meat on the back of the rim, you can take some off to get more offset. If there is not enough meat, then you leave it alone and don't risk integrity.

I agree, some people like that look.

I do not understand the stretched tire look at all. It looks bad and serves no functional purpose. The only 'race' cars out there I have seen run stretched tires are drifters and well they aren't real racers. Yes it will somewhat increase the response of your tires, but if you run the right type of tires at a decent pressure the added response will be minimal. If you go with a crazy stretch like a 225 on a 9.5" wheel it is purely for looks and you might as well add an underglow and fart can exhaust IMO.

If you like that look and want to do it great, but expect resistance from those of us functional people out there.

As for the OP I'd pick the 235 option.... actually I'd really prefer a 245 on an 8.75" wide wheel. I like to keep a square sidewall with as much tread on the road as the tire allows. Pick a tire with a stiff sidewall (most summer tires suffice) and air it up about 3-5 PSI over recommended (NOT the number on the sidewall of the tire that is the maximum inflation pressure and you should NEVER exceed that)

For me I'd run the following on my spec.B:

215-225 on 7"wide wheels

225 on 7.5"

225-235 on 8"

So you just hate on whatever you don't understand? Everyone is allowed to have their own opinion/style. Just because it's not mainstream that doesn't mean it necessarily bad. There is also a big difference between stanced car and ricer shit.

It's not as simple as "enough meat", if you shave off the back padding, you take out the aluminum between the lug nut and the hub/rotor. If that part is too thin, it's prone to cracking then it won't be fun at all

So what about an 18x875?

Width and height?
