15" or 16" Fuchs, Decided......going with the 16" Options

[JStroud]

I want to get another set of wheels for the white car, the 14" Fuchs are too limited on tire selection, plus too high RPM at freeway speeds, odometers off and so on.

Now the desicion, I've been offered a set of 16 x 7 Fuchs, but through my research if I understand right I would need just the right size tire then still have to pull the back fender a little to make them fit......if thats true, not sure I want to do that. (Narrow body car)

Then yesterday I came across a set of 15 x 6 Fuchs, both sets are in very good condition and about the same price.

Haven't done much research on 15" wheels, only have my iPhone this week, limited search ability.

So what do the experts say, which will fix my issues better, 15" or 16".....and fit my car the best.


Thanks

This is a lengthy topic with several variables. But think about taking measurements from the disc face to the closest inner obstruction and closest outer obstruction. This will determine the offset of the wheel. (the difference in measurement from the outer rim to the inner rim from the mounting surface)

So if you have a 6" wheel and there is 1" more room from the disc face to the inside than there is to the outside you have a 1" offset. (hmm... I think) someone will correct me if I'm wrong. Anywho, be sure to measure before ordering wheels. I think someone has a link to a wheel chart showing what fits on our cars.

Then there's spacers that will center the wheel in the opening. That opens up the options but adds the replacement cost of wheel studs in place of bolts.

15" tires are very difficult to get in a staggered size. I had to move to 16" wheels to get tires for the Alien. The next time I tried to purchase tires they discontinued the rears I liked and I ended up having to purchase 4 tires to have a matching set. (IMG:style_emoticons/default/dry.gif)

Wheels now a daze (IMG:style_emoticons/default/wacko.gif) tend to be lighter than the old 15". So unsprung weight is usually better with 16" wheels.

Tires can be ordered in different heights to correct speedo readings or actually change gear ratios. You may want to consult with your favorite tire shop. They can get you into the tire that fits your needs. But you may need to talk to a performance tire guy. Not the guy that won't sell you anything that didn't come on the car.
