Hi all, I have just purchased my first mini its a 1998 Rover Mini Cooper Sport with the factory 13" wheels, I'm wanting to give it more of a classic look and have always wanted 10" minilites or similar wheels. I'm not very knowledgeable on how gear ratios and all that works, obviously putting 10" wheels will up my rpm's but hamper my top speed, I'm just hoping to find someone who could tell me how much it will change the rpm's and if its even possible to fit 10" wheels over my factory disc brakes, any info would be greatly appreciated!

you will need to change the discs. like http://www.minispare...~Kits.aspx|Back to shop



then you will need to change the speedo drive parts to suite.

Before you mount 10” wheels/tires, you might want to consider how they will look under those flares.

Sportspack and tens can work, I’ve done it. Wouldn’t worry about the speedo, it’ll over read not under, if I’m doubt speedo app on your phone will help relearn where the various speed points on the gauge are. Enjoy!

There is virtually no difference in gearing between a 13" and a 10" wheel. The 10" uses a better higher-profile tyre (145/80 x 10 or 165/70 x 10 as opposed to a 175/50 x 13).


To change to 10" wheels you need a new set of 7.5" discs, a pair of Cooper 'S' callipers and a pair of drive flanges. Mini Spares do a good conversion kit.


With 10" wheels, if you fit the 4.5" x 10" ST-Spec Minilites, you don't actually need wheel arch extensions, although if you have had the 13" wheels the wheel arches will have been rebated to allow for the very wide tyres. You could change to the very attractive narrow Group 2 arches which allow a chrome trim strip to be run all the way from front to back over the arch extensions. That looks really good. You can then fit 5" x 10" wheels with 165/70 x 10 tyres.


Once you have fitted 10" wheels you will be pleased at the improvement in overall ride & handling and with the improved road-holding in the wet.

Remember though, if you loose the sportspack arches, you will need to consider what you are going to do about the wings and A panels as these will have been chopped considerably to allow the fitment of the arches and wheels.
