I just bought some used 22's with 265/35/22 tires on them. But 1 of the tire needs to be replaced and the other 3 are in great condition. I want to change 2 of the tires to 285/35/22. So I would have 265/35 in the front and 285/35 in the rear. I would like to change all 4 but tires are so expensive and the old tires still have at least 15k miles on them. So is this a good idea?

Although the difference is minimal, running tires of different circumference on front and rear axles is not a good idea, especially on a vehicle with an all-wheel drive system as sophisticated as the Range Rover. If you must run a wider tire on the rear wheels, try to pick one with the same overall circumference / rolling radius as the front ones. In your case (if you can find that size and your aftermarket rims can take their width) a 305/30/22 rear tire would be a better pairing for your front 265/35s - especially since these are likely to be a little worn already - and minimize risks of electronic and mechanical problems with your driveline in the long term.

The tires on these heavy beasts take a pounding and are the only contact between the car and the road. Don't skimp on quality or mess around with mis-matched sizes, it's not worth the risk - the car's ecus will have a fit.

Super Duper.

Just remember that if you have a pair of tyres narrower or wider front to back - there's no chance of rotating your rubber.

The 285/305's might work on the rear suspension, but have clearance/rubbing problems when you fit them to the front end & then you can only rotate the tyres side-to-side with different sizes front to back, let alone wear out a tyre even sooner ?

You've heard the old British saying, "If you can afford to buy a Range Rover-than you can afford to run one" comprehendie !

Cheerio,
