So this is me showing my clueless side but how much does it matter if you deviate from OEM tire diameters?
In this case I am talking about going less wide than stock but keeping rim diameter the same. How far can you safely/mechanically go before it will cause issues.
I just genuinely have no idea what is ok and what is not in this regard and google hasn't been enormously helpful so far.
Any rule of thumbs on % difference to stick to?
This would be on a modern car with electronics up to wazoo so need to make sure it doesn't fuck with any wheel speed sensors too much either.
TIA
