245/45/17 instead of 225/45/17


Recommended Posts

What do you think? Anyone tried such replacement? 

 

Fuel consumption will increase - hopefully only a bit - but sidewall height will increase by about 9% so the ride should be more comfortable. 

 

And it should look better ;) without going for 18".

 

The price difference on Uniroyal RainSport 3 is only about £15/piece.

45 is percentage of the width - not constant value - so tyre is higher - 110mm vs 101mm.

If you are looking to increase the sidewall height why are you complicating things by doing it via the width (225 > 245)?

 

Would it not simply be easier to increase the profile (45 > 50) and keep the current width?

 

This is what I've done...

My speedo now perfectly matches the GPS @ 80mph and I haven't suffered any tyre / rim damage from potholes since.

Higher profile means bigger speedo difference. 

 

I know that I'll need to inform insurer. 

 

The ride is perfectly fine for me ;) I just would like to have a bit more rubber sticking to the road ;) lead foot ;)

 

Maybe 235/45/17 would be less problematic ;)
