I have no knowledge of tires at all, outside what the numbers are supposed to mean.

Does toyoguy's post mean that all the sizes listed will fit the original equipment rims on the MS6? If not, is only the OEM size recommended on that OEM rim (215/45R18)?

The section you quoted lists all the 18" tires one might choose for a Mazda6/MS6. Note the rim widths listed after each tire size-- the only sizes that should be used on a 7" rim are the 215/45 and 225/45. Since the OEM rims are so narrow, if you want to use tires that are wider than OEM, you really should get wider wheels as well.

Probably. That setup sticks out 25mm (1") over our stock setup ([225mm - 215mm] / 2 + 60offset - 40 offset = 25mm).

I ordered Sunny SN3970 225/50 R17 98W. ....


First impressions:

..... I'm going to spank them in about 500 miles and see how they handle.[/b]
Finally getting back with a post-spank review. The 500 miles stretched into 5,000 miles. Read the note at the bottom as to why I was delayed, it may help someone avoid a lot of frustration.

Noise - Good. This tire is quieter than the stock Michelins and Exclaim UHP.
Appearance - Great. Looks really good in the well and from behind. The foot print fits the 6 well.
Handling - Not very good. Bad for the aggressive driver. The compound is not as sticky as an Exclaim and really likes to squeal and chirp. These tires are 1 inch wider than the Exclaims I ran, but the Exclaims were much stickier. On the up side, these tires are good for folks who drive tons of highway miles. These tires go straight.
Price - Great.

The delay. The same day I had the tires mounted, I hit a pot hole in a rain storm. I forgot about the pot hole. I started to hear rubbing / popping noises when I would turn my steering wheel at low speeds. Think: sound of clean tupperware. I thought it was the tires. I removed all the tires and checked for rubbing, I tried different pressures, I rotated tires. I went to a different tire shop (Discount) and those guys actually said, "you definitely have fitment issues...you need to buy a smaller tire". Luckily, I told my lube tech about it and he checked. He says, "ball joint". I go to a mechanic that I trust (with a Mazda you don't go to a mechanic very often ). He confirms the problem is mechanical and says I probably hit a pot hole or curb. Bang, the memory of the pot hole comes back! Problem turned out to be the passenger lower control arm. Once that was fixed, no more rubbing noise and no more hating the Sunny tires.

2006 Mazda 6i, base model.
Waiting for the next LeatherSeats.com GB!

The high offset of the OEM wheels should help prevent rubbing. However, it is NOT safe to run such a wide tire on a 7" wheel. A 245/45R17 tire needs at least a 7.5" wheel, and should really have an 8.5"-9.0" wheel to properly control sidewall flex.

In the first post of this thread you can see the widest tires recommended for a 17"x7" wheel are 225/45R17 or 225/50R17.

Suspension ride height is immaterial for determining tire to fender clearance. If an interference problem exists, it will show up at maximum suspension compression, which can occur regardless of ride height. Lowering a suspension only makes an existing issue show up more easily.

Hi,

we are stationed in Europe, and bought with US-Spec a Madzda 6 3,6 ltr. tires size P235/45ZR18.

Over here in Germany nobody can tell me if I can use smaller tires. Because l am looking for some winter tires.

And I pay here around 270 USD each tire.

Can somebody help me????
