my fronts wheels are 16x7 and i know i'll be able to fit 205/40/16's easy with a bit of scretch. i was wondering would it be possible to fit 205/40's on 8" width? or should i go with 215/40's? thanks!

 

you could fit 20/40's on a 8" rim, but why would you want to???

Isn't the point of using a wider rim, the ability to run a wider tire...

 

Actually 205/40-16s will actually bulge on a 7" rim and look "stretched" on a 8" rims

Most the 205/40-16s I have seen have an approved rim width of 7-8". Every tire is different, look up the spec sheet for your specific tire and see what rim it is designed/approved for.

You should go for a tire that fits your car. Find something with an overal diameter +/- 3% of stock and no more than 20mm wider if you have stock suspension and offset.

 

so 205/40's should be able to wrap around a 8" width rim. its just i like the "stretched look" i just want to make sure it will be safe to run with. i have 205/50's on the 16x8 and it stretches fine. but i want to run 40's or 45's.

Every tire from every manufacturer is different. You have to look up the spec sheet for the specific tire you are getting and see the range of 'approved rim widths'.

 

cool thanks!

Like neri said, use the proper size for your car. Don't just say "I want to run 40's or 45's" or you're likely to wind up with tires that rub and/or don't fit.

Which model, version, and year is your car?

 

1993 honda prelude. and anything 50 and up will rub.

Rubbing is mostly a function of three things:

1. The offset of the wheels, which positions the wheels in the wheel wells (out away from the car or in towards the car);

2. The width of the tires; keep it within 10-20 mm of stock and you shouldn't have problems; and

3. The outer diameter of the tires; keep it within 1 percent of stock and you shouldn't have problems.

The '93 Prelude came from the factory with either 185/70-14 tires (Prelude) or 205/55-15 tires (Prelude Si or Prelude VTEC). In either case, the best 16" size for your car is 205/50-16. 205/40-16 and 205/45-16 are much much MUCH too small (unless you're going for a low rider look with teeny tiny tires); for example, 205/40-16 is 7.2 percent smaller in diameter than stock!!! Don't do it. 205/50-16 is perfect for your car, because the outer diameter is within 1 percent of stock and the width is 0-20 mm different from stock. Stick with 205/50-16 and you should be fine.

If 205/50-16 is rubbing, then the only possible reason is because your wheels are the wrong offset for your car, in which case you should get wheels with the proper offset. Don't compound your error with the wheels by making a second mistake and getting tires that are too small for your car.

Most 205/50-16 tires are approved for mounting on rims that are 5.5-7.5 inches wide, and should not be mounted on 16x8 rims.

 

good info! i got some old school volks mesh wheels with a 35 offset. and im slammed to the floor. rubbing is not a big deal to me. im on 205/45/16 im not rubbing. and they seem to be just fine for my car. but ima try to figure something out the my 16x8 wheels. the front (16x7) is no big deal. i jus wanna be able to get tires on my 16x8 with just a bit of scretch.

 

205/45-16 is WAY too small for a Prelude, almost 4 percent smaller in diameter than stock.

Preludes use bigger wheels than other Hondas.

205/40-16 = Civic
205/45-16 = Integra
205/50-16 = Prelude

16x8 are too wide for the tires that fit Preludes. Get wheels that fit the tires that fit your car. Sell the 16x8 wheels to someone whose car takes wider tires. Don't use the wrong wheels on your car, and don't use the wrong size tires on your car.

BAD advice.
