defenders....check your tyre size (-:

[Tom D]

I've got 265 75 16 on mine Dean, same radius as the 235 85 I think...

[Stubby]

Its the aspect ratio isnt it ? 235/85 is 85% of 235 = 199.75 = aspect ratio. 225/75 has an apect ratio of 168.75 . Least I tghink thats what it means .....

I run 285.75.16. When my speedo says 50, I am actually doing about 55mph.

It all goes back to a time before low profile tyres.

 

If you bought a SWB you had 6.00x16 tyres. 6+16+6=28" diameter.

 

If you bought a LWB you had 7.50x16 tyres. 7.5+16+7.5=31" diameter.

 

The SWB and LWB had different gears on the speedometer drive cable.

Just be careful of using 4wd and mixed (front/rear) rolling cirmcumferences and hard surfaces - you can pop diffs. Not a likely configuration on the average defender mind.

I have 235/85/16 on the front and 7.50 x16 on the rear.

Will it kill my Landy?

[Rich Rule]

I think the tyres will be ok but being a Landy, it is probably terminal, only a matter of time.

 

(I'll duck now ready for the barrage)

Exactly. So a 235/85 is 10% (ish) bigger than a 235/75. You can play tunes with the width vs aspect ratio to achieve a certain size. I used to just fit the standard Avons, I've forgotten the size now
