Im getting some Volks in a few days, I dont really know what width I should get? Do i need 17x7.5? 17x8.0? And what tires size is recommended? What size are you guys using? And size tires, brands, anything I should know before I pick up the rims.

Which MINI do you have, model and year.
What suspension- stock or lowered? Any plans to lower?

What do you use your MINI for- Street only, track, autocross, driving school events?

Do you drive in dry or wet areas, any chance of needing to drive in snow or cold weather less than 40 degrees? Any winter tires?

What is your budget for tires?

Stock MINI size is 17x7 +48 offset 4x100 bolt pattern.

17x7 is easy to find, 17x7.5 is workable, 17x8 is possible.

17x7 usually gets stock 205/45-17 or 215/45-17 (a little taller than stock but fits stock suspension). If lowered suspension then 215/40-17 is possible and gives more clearance.

17x7.5 fits the above tire sizes fine or even better in the case of 215mm wide tires.

225 mm wide tires don't really come in MINI friendly sizes, many are a bit too tall to avoid rubbing.

One exception is Yokohama S.Drive in 225/45-17 at 24.8" tire diameter but most are 25" tall. Stock is 24.3" usually.

17x8 rims allow for some tire sizes that are much wider but you have less clearance on width so you have to be more careful about wheel offset and rubbing on the inner rear wheel arch plastic against the outer treads.

Then 235/40-17 will fit, using 17x8 rim with about +40 offset.
This tire fits rims 8 to 9.5" wide and tire diameter is 24.4".
This will work with stock suspension or lowered suspension -about one inch drop.

To get a little more clearance in the back you can use lower adjustable control arms to increase rear negative camber. 2005 and later MINI have a small adjuster at the bottom of the lower control arm to allow for about 1/2 degree of camber adjustment, earlier MINIs don't have that.

Thanks for the help, im not to wooried about the budget on tires, just tryin to keep it under 1k, since i will be getting 5 rims. I use my car for street only, i have a 2007 MCS its not lowered yet, but I do have H&R coilovers not installed yet. I live in Cali so no need for winter tires. I've heard only people getting 17x7.5, so what would you recommend now?

If the H&R Coilovers allow for ride height adjustment you will be fine with any tire of about 24.4" tire diameter or less.

17x7.5 rim is fine. About +38 to +45mm offset range. +38 puts the wheel closer to the outside of the wheel well while +45mm is a closer fit to stock. Both can work.

For tire size you can choose-
215/40-17 which is smaller tire diameter but gives you good selection of tires and works with a lowered MINI, not really a good choice for stock suspension.
Or 215/45-17 which gives very good selection of tires and is taller by a little and works with both stock and lowered suspensions.
You get a little speedo error either way.

For a tire that is very close to stock tire diameter but wider and will work with 17x8" wheel you can shop for 235/40-17 tires.

Some example tires:
Extreme Performance Summer tire-
Dunlop Direzza Sport Z1 Star Spec 200 treadwear
see
http://www.tirerack.com/tires/tires....e1=yes&place=1
215/40-17 $124 each
215/45-17 $125 each
235/40-17 $139 each

Very good handling wet or dry, better priced than some other Extreme tires, moderate street comfort, faster wearing likely less than 2 years.

In Max Summer tires-
Dunlop SP Sportmaxx 240 treadwear
Goodyear eagle F1 GSD3 280 treadwear

And many more choices.
You can search for the tire size you are interested in and there are many threads for each size.

Try to find a tire that will fit your rim of choice with tire diameter as close to stock size as possible = 24.3".

Once you use a tire with a tire diameter that is too small or too large you automatically get the error.

If you use a scan gauge II to connect to your OBDII connector you can adjust the displayed speed and get very close to true speed but you may need another car to monitor your speed so that you can adjust.

Once adjusted you can just watch the mph display on the Scan Gauge II and ignore your speedo.
