Thread: Discovery 2a tyre up-size

Legally I think about the most you can go is 245/70/16 although I beleive you can get up to about 265/75/16's under the gaurds with out doing any mods.

I went from 18's to 16's and fitted 265 x 70 Bridgestone 694 A/T's. They seem to be a good size for a D2 and don't rub anywhere even without a lift. You might be able to go bigger without issues but that would need to be answered by someone else.

Are they legal? not sure...

cheers,

Thanks for some quick replies. Legal??? Well in Vic we can legally increase overall wheel diameter by 15mm making a legal up-size somewhere between a 245/70R16 and a 245/75R16 since I started with a 255/55R18 which is 737mm overall diameter. I am liking the idea of a 265/70R16 though if folks reckon they don't foul in the gaurds. Keep the ideas coming!

On my 2003 Discovery HSE, fitted with a 2" suspension lift, I have 255/70R16 tyres on a set of genuine Land Rover 16x7.0J rims. The tyres are Mud Terrains and they catch on the front suspension (the brace bar that runs from the front suspension towards the rear of the vehicle on the chasis) near full lock. They also put the speedometer out by 3km/h - i.e. so when the speedo reads 100km/h, the vehicle is traveling at 103km/h. I believe that from factory most vehicles, in order to meet the Australian requirements, usually come out with speedometers 3km/h overreadering (i.e. so when it says 100km/h your actually only doing 97km/h) in order to compensate for tyre wear. If this is the case, then my speedometer is actually 6km/h out when compared to the factory size tyres.

I'm running 255/70 x 16 S/T's. No lift. They don't rub anywhere. Calc' difference is approx' 3.8% oversize ... by GPS vs speedo it's about 5km/.hr difference (ie:100km/hr on the speedo = 105km/hr by the GPS.

245/75-16 is fine without lifting

I run 265/75-16 with a 40mm lift. Need to adjust the steering stops to prevent rubbing on the front.

Make sure you get LT tyres.

Thanks for some more replies.

Try not to go too big because it will affect your gearing. I am running 245/75/R16 Cooper ST's on my V8 auto and I noticed a difference in gearing, I believe it is more noticeable on autos. My speedo at 110kmh is almost 7kmh out according to overhead advisory signs on western hwy.
