Hi all, in the new year I'll be due for new tyres, but I can't find any info on what load index we need to run on our cars.

 

A normal tyre has a load index of 91, which allows a load per wheel of 610kg, is this enough for ours? Or is it necessary to go for an XL rated tyre, because they're coming up about £20 more each!

Load index is based on static load capacity of a fully laden vehicle (rated up to 130mph)

 

91 Index has a 610kg Load rating.

 

Assuming equal load per tyre (its not, but its close enough) :

Stock 300zx LWB TT Auto (Heaviest variant) = 1590kg

4 adult passengers = 350kg

Luggage = 100kg

=2050kg/4 = 510kg

 

91 Index tyres is fine.

 

Plus a typical 300zx is far less likely to be fully laden in comparison to your average family estate.
