got michelin energy on atm brand new basically but when i replace can i get some wider ones- they look so skinny next to my vtr alloys, or do i have to get 1.9 alloys to go wider ? i will check sizes tomorrow

The general rule when putting wider tyres on is if you go wider you need to reduce the profile to compensate, because you will be changing the gear ratios. ie: 185/55/15 - 195/50/15

1. what car do you have?

2. what size wheels and tyres do you have?

3. this is the wrong section.

Hey Matts206, I'm not disputing what you're saying, but I'm not understanding the principle of the relationship between the width of the tyres and the depth of profile and gear ratios!? Could you elaborate on that a little?

 

 

Just had a coffee and woke up. Makes perfect sense.

 

55% of 185= 101.75

 

50% of 195= 97.5

 

Got you
