Car tyre load rating any downsides to increasing ?

RichardPitman

My C-Max is fitted with W89 load rated tyres as standard, but when I looked on the Blackcircles website all the recommended tyres were either W91 or W95 rated. I ended up buying W95 Michelin Primacies, which are actually a few quid less than the W91 equivalents.

So far as I can determine, fitting tyres with a higher load rating is all good, stiffer sidewalls should be better on a laden tow car ?

Just wondering what the possible downsides could be ? Car seems fine to drive on these tyres.

Harsher ride perhaps ?
