Hi
Can anyone tell me if there is any reason why I could not put normal road tyres on my Rav. I have no itention of going off road at all.
Thanks

Just looked up this old post.....its to do with the load index number on the side of the tyre.....
"Here are some details about tyre markings:
Sidewall Markings
185/60 R 14 82 V
185 - Nominal section width expressed in millimeters.
60 - Ratio between nominal section Height and nominal section width. In practice this indicates the series of the tyre.
R - Radial construction tyre.
14 - Rim diameter, expressed in inches.
82 - Load index. Indicates the load carrying capacity per wheel.
V -Speed symbol. Tyre's maximum speed.
Speed Symbols
Symbol Km/H MPH
Q 160 100
R 170 105
S 180 113
T 190 118
H 210 130
V 240 150
VR >210 >130
W 270 168
Y 300 186
ZR >240 >150
[color="#FF0000"]so your 235/60 R 16 100H have a load index of 100, and speed rating H of 130mph.[/color]
4x4 vehicles tend to be bigger/heavier, and therefore require a higher profile tyre (more tyre between rim and ground) with stronger carcass and sidewall construction to withstand off road lumps and bumps and sharp objects.
I am not an expert, but I would expect a "road" tyre designed for a 4x4 would still be different to the same manufacturers "road" tyre for a hatchback/saloon.
I personally would get advice from a tyre specialist before fitting anything not seen as standard for your Rav.
The specs above were borrowed from www.prielli.co.uk and probably also available from the other manufs. such as Dunlop.
Hope this helps.
