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????[/b]
What model year do you have?

Great list, that's really useful info - I wished I'd found this before I went and brought some 225/40/18 tyres only to find out that my wheels were only 18 x 7 inches. They are JDM OEM rims with 215/45/18 OEM tyres. Is it detrimental to the overall handling of the car if I get them put on or is it just better and wiser to just cut my losses and get 225/45/18 or 215/45/18 tyres instead??

Hi, just a query regarding the 225/40 and 225/45 size tyres, how come the 225/45 can fit 7" rims while the 225/40 can't? Aren't they the same width?

The shorter sidewall of the 40 series meas the sidewalls will be bulged out more than the 45 series due to the narrow rim. This can lead to instability, and possibly even the tire rolling off the rim in the extreme case.

On any "low-profile" tire (pretty much anything 50 series or lower), both the section width and aspect ratio are important to determining the safe rim widths.

I was thinking about getting 215/35/18s for my 6 but i dont see that on the list. There is however a 215/40/18, why would a tire with the same width and diameter but less rubber height not fit? I am sure I am missing something I am very new to this. Thanks for any response.

Because they aren't the same diameter, due to the 40-series tire sidewall being taller than the 35-series.

If you downgrade to a 35-series, the average diameter will decrease from 24.8 inches to 23.9, almost a full inch less. This will also make your speedometer 3.4% too fast, which is well outside the 2% difference that's allowable when changing tire sizes.

Oops

Quick question, I want to know if I have to switch out a set of tires I had bought on ebay. I had apparently been half dead when ordering and didn't pay attention, but I must have searched for 215/45/17. (Running stock 17s)

Will these fit and run fine on a 2004 Mazda6 (Stock rims 17)

I see on the list 225/45/17 (IIRC)

Thanks in advance

I would appreciate some assistance. I have a 2004 mazda 6 with 215-50-R17 all seasons needing replacement. I can't find a decent replacement in that size, but can find 205s or 225s (other specs the same). I see the 205s are not onthe tire list here-but I have varying opinions as to what would be best here-Any Advice?

iv read over the thread and have even tried out the prescribed size of 225/45/18 on my 18in x 8.5 width. Unfortunately that size was far to skinny for my 8.5 width tires. since then iv check and rechecked the thread and gone to numerous shops with little success on what size is the right size for my wheels. thus far iv narrowed it down to 235/40 or 245/40....any thoughts on this....am i far off...please help a desperate man out.

There are a good many "decent" tires in that size! 215/50-17 is the OEM size for the later iterations of the car, and while there are not 150 choices, there are plenty of very good all season replacements. Did you go to the Tire Rack site? There are 58 tires they carry in that size; 36 are all-season tires, at many prices.

I have a 2004 Mazda 6s Sedan, with the 6 cylinder engine. I am looking for replacement tires for my vehicle. The originals are the Michelin Pilot HX MXM4 size 215/50R17/93V on the original rims; I've done all my research and have been looking at tires in the same exact size, but most have load ratings of 95, instead of 93. Is it safe to use the 95 load ratings on my vehicle, I was considering the following tires: Bridgestone Turanza Serenity 215/50R17/95V; Continental Extreme Contact DWS --in size 215/50R17/95V or 95Z, -, MIchelin Primacy MXM4 size 215/50R17XL 93V BSW; yokohama S. Drive--215/50R-17 95W XL B;--Toyo PROXES- 215/50ZR17 95W (from what I've read I need a tire with a load rating of at least 93 and speed rating has to be V or Higher.) I'm looking for all season tires. I'm looking for a tire that handles well, and can provide decent winter traction as I live in Michigan! Which is a good tire that other people have put on their Mazda 6S's or another comparable tire that can be reccommended? Please help

95 is fine. Going higher than a Load Rating of 93 is not a problem (91 with the 16" wheels), but going lower is not wise for a lot of reasons.

In case it helps, you can also look into tires with a Speed Rating of H as well. They are suitable for the 6, and they also tend to have a longer treadlife.

As far as your suggestions, if you're sticking to all-seasons, stick with the Continentals. I've heard nothing but good things about these tires, offering excellent dry and wet traction, along with outstanding snow traction for a performance all-seasons. The Bridgestone is more of a touring tire, which you may not like due to it's lower performance limits. Michelins as a whole are simply overrated and overpriced, and snow traction is a bit scary with the Primacys. The Yokos you listed are summer tires, so I wouldn't even consider them if you plan on driving in ANY snow/sleet/slush or any weather under 40 degrees. Summer tires in general are simply deadly in the winter.

You won't consider getting a separate set of winter tires?

thanks for the help!

Yes I would consider a set of winter tires. What are some good winter choices for my car that you can suggest? Should I order tires with the rims attached, or just order the winter tires and have them put on my current rims. I'm not looking to spend a whole lot of money I'm thinking of staying with the 17" rims, two of my current 4 tires are pretty worn. I saw a post about performance winter tires. Thats probably what I would get.

Personally, I'd find a set of cheap 16" steelies, or used 16" rims from a Mazda 3, 5 or 6 from a junkyard or Craigslist, and get a set of 205/60-16s (the OEM size) for winter tires. Not only are the 16" tires less expensive than comparable 17" tires, but you also save the wear-and-tear of both the tires and rims, as well as not having to pay $20 per tire, to swap them on and off your OEM rims twice per year. I bought a set of 16" steelies with tires from Tirerack when I first got my '04, and I'm using them again on my '10 (with newer winter tires).

As for winter tires, I ran the Dunlop WinterSport M3, and they were excellent winter tires, offering great traction and control in rain, snow, slush, etc. as well as offering excellent handling for any "spirited" driving on the drier, sunny days (unlike regular winter tires that tend to get "sloppy"). The replacements, the WinterSport 3D, are also very good, and are used by more than a few other 6 owners. Michelin also makes some decent winter tires, as well as Continental with their new ExtremeWinterContacts.

I'd shy away from Bridgestone Blizzaks, since I've owned two different sets of them, and I've found that the useful winter treadlife to be lower than other brands. I've gotten more seasons of useful winter traction from all other brands.
