Thread: SIII wheels, speedo, and tyres? HELP!

You could try 205 r16's (Rangie tyres) or 235/75 r16's (disco).
A bit smaller diameter but will fit on ya series rims.

If you are after lighter steering the 205s should be the better of these two. It was designed for 6.00 or 6.50 - I haven't seen any of the latter for years, but 6.00 are available, at least in straight bar tread, as they fit the original Jeep and also the relatively recent Suzuki (now called Sierra).

Steering should not be too heavy with 7.50 tyres though, provided the tyre pressure is correct. If it is, either you are too used to power steering, or there is excess friction in the steering, most likely from the steering relay being dry, and if left that way will wear badly. Jack up both front wheels and the steering should then be quite light. But even if fixing the relay solves the steering problem, it won't fix the speedo reading.

I see theres a bloke on fleebay doing 205/80/R16 retreads for $389.00 + freight. Hes doing different size retreads.

Whats the disadvantages of using retreads? Ive got retreads on mine , thats the way it came. w.

At a second look it was $299.00 +

Which way is the speedo out? Land Rover speedos are prone to error, and most are excessively enthusiastic. My first LR read 60 at 50. I wondered why everyone else was speeding, and how the elevated driving position made everything feel slower. Then I realised what was wrong.

Don't select your tyres to match the speedo.

I "calibrated" mine and it is accurate.

I followed my wife's car in my series 3 while we were both on the mobile (hands free of course) and got onto a long straight bit of road. She sat on 60 for a couple of k's, then 70, then 80, all with the cruise control. I neither gained nor lost distance, plus the odometer/trip meter was very close to spot on give or take 50 metres. I figure thats good enough for a 36 year old car, although having only just clocked 50000km (for the first time too) it is still just a baby. From what I hear many series speedos start to play up from there onwards.

Same here for the 2a - checked by various methods. More than can be said for the speedo on the 110, which reads 7% high.

Will 235/75 fit on a series 5" or 5.5" rim? I thought the min rim width was 6.5" or 7"

205s are about the same as a 6.50 tyre.
