235/40/18 on F30

wdeerfield · 02-05-2016, 08:51 AM

I am looking to pick up a CPO F30 335 and i am curious if my existing snow tires will be okay to use on it.

The stock tire size is 225/45/18 contisportcontact 5 SSR and my snow tires are 235/40/18.

According to the tire size calculator they will be about .5" shorter than the stock setup. Would there be any harm in running this setup? The tires are Yokohama IceGuards mounted to 18x8 et 32 wheels. while i know it will affect my speedo, is there anything else i should be concerned with?

Thanks in advance.

The wheel gap will increase and the ground clearance decrease. I don't see any other issues.

thats what i was thinking. id see a reduction in ground clearance by 1/4" and a 1/4" increase in room between wheel and fender

Well i put them on last night. 18x8 et32 with 235/40/18s and looks good to me. Now to sort out the TPMS light. besides swapping to the newer sensors is there anything i can do to "fix" this?
