16" or 18" Rims/Wheels

Hello,

I have a 2006, Mazda 6 which came with 18" Rims and low profile tires (215/45R18 93H). Looks great, but I dont like them because they seem to wear down too fast....i was told they wear down faster because they are low profile tires, 'regular' tires would last much longer. is this true?

Since i am more about function than style i just want what ever is best economy wise...would 16" rims allow me to have more normal size tires (not low profile) and is it possible to switch to 16" rims, without doing any modifications to the car whatsoever?

Cheers,
Danny

The tire's profile has nothing to do with the tread pattern and subsequently wear. That is total BS. A comparable 16" or 18" tire are going to wear the same, all else being the same (temperature, use, inflation, balancing, rotation, etc.). I would run from whoever told you that.

The Mazda6 comes with 17" rims that had 50 series tires on it. I imagine with a 16" that you could get away with a 55-60 series. That will make a difference in the ride, the ride will soften up due to the taller sidewall but the handling will suffer as the tire will flex more in turning and braking.

It has nothing to do with mileage, but if you want a taller tire for a smoother ride, a 17" might be a good way to go.

you can run 16in wheels no problem. mazda also released some mazda6's with 16in wheels and 205/60/16 tires. the 17in factory wheel used 215/50/17 tires. if you use 16s, just make sure you have the correct bolt pattern wheels with the correct offset.
like he said, profile doesnt play a part in wear for tires. my guess is that they are either a performance tire with less tread, or they are just cheapo tires that wear down faster.

what they said.

though I will say anything smaller than 17s look odd to me on a 6.

Dale is totally wrong.

If you study tire dimension tables, it is obvious for a given tire width, the lower the aspect ratio, the wider the contact patch. Go to any tire store and you will see the same. A 70 series tire will have a contact patch an inch of more narrower than the tire width. I have 45 series tires where the tread contact width is about the same as the tire width.

A 215-55-16 will wear much better than a 215-45-18, and have a better ride, and less sencitive to bad alignment. But with less cornering capacity and less response to steering inputs.



I did not like the ride on the 17" rims, and the exposure of the wheel lip, that was wider than the tire. I went with 215-55-16 with Mazda-3 6-1/2 x 16 x 52.5mm wheels (BMW look), with DWS tires. No regrets.

My 16" set-up. If I need 1g cornering, the Twin Turbo Rx7 comes out of the garage!
