Anyone Know About TIRES, I have a question.

[havoc]

On my car there are 225/45, 17 inch, Z rated, if I drop some 235/45's then that tire should be a lower profile, is that correct?

thats an odd size for 17 i think, 245 is usually what people go with for the jump from 225

you put in your car - they show you a pic of it and all the wheels and tires that they have that will work on it and what they will look like on your car.
they are cheap too.

hot damn tamale.

No, it is not a lower profile. It is just a wider tire. The 45 is the height you are refering too. If you went 235/35/17 then you would be one size wider and one size lower on the profile.

Appreciate the replies, but its a 235/45 I am looking at, I know I really wont be able to tell the difference, just wondered if it will be a lower profile, guess not.

Thanks gentlemen.

i know the friction between them and the road make your car stop, thats about it. occassionally i'll put some armour all on them.

The first # (225) stands for the width in millimeters, the second (45) stands for the percentage of the width in relation to height. So, yes, it would be a SLIGHTLY lower profile, but it would also be 10 mm wider. What you need to consider is if the height is slightly different, you have to worry about it throwing off your speedometer calibration. When switching from let's say, a 15 inch rim to a 17, the combined tire and wheel HEIGHT bottom to top has to be the same as it was with the 15, or you have to recalibrate the speedo. Even though your change is slight, you should still check to see how much it would, if any, throw off that ratio. If it's only 1-2 mph, then it's no big deal. Best thing to do is ask the people installing the tires to look up that info on thier computer... your change is so slight that I don't think it'll make much of a difference though...

Ok, so putting 235/45/17's on is not going to f up my car in any fashion correct?

as long as the wheel wells can support there size you should be fine, what kinda car?

Nope. But be sure that the width will not interfer with you turning the wheel to the stops. I dont see this being a problem though.

just make sure you can turn the steering wheel lock to lock without the wider tire rubbing the inner (or outer) fender well when turning with the wheel all the way to either side...

it SHOULD support that width, but I'd make sure first on the width to make sure it won't rub, ESPECIALLT if it's lowered.... and if it IS lowered, make SURE you get the camber kit to compensate for the increase in negative camber...

 

[naturally anabolic]

you'll be fine with the tire, the bmw's wheel wells are very large and can accomdate almost any tire you give them

Some excellent advice , thanks guys. peace
