Anyhow...getting to the point, am riding on 16" stock rims, tire size: 225/55R16, am planning to upgrade to 18", tire size: 235/40R18, I drive a Holden VZ 2006 V6, the problem is this that the new rims that am going to buy i.e. 18" won't fit my car as they're for Holden VZ 2008 model specifically, the shop am buying the rims from, I know this guy, he's a good friend of mine, have bought a lot of tires from him, but not rims, he recommends buying the rims and then grinding some mm's from the middle (The middle hole,I guess its called the hub? :\ ), as the stock rims middle hole is a bit big i.e. of 16" then 18"s


What do you guys think of grinding some mm"s from the middle of the rims, is it safe ? :think:

Below are the pics for 16" and 18" rims,

The proper term is hub bore or center bore. Look up the size for both vehicles. You'll need the bore of the new wheels machined to the size for your car. Definitely don't attempt this yourself. It should be done by a machine shop on a mill or lathe. It should cost less than $100USD to have the 4 wheels done... I usually see it priced at about $20/wheel.

Thnx for correcting me, I was just concerned about the safety... so it means it's safe to do this?
And off-course am gonna get it done by a machine shop, well its not gonna be that expensive here, may be around 100 Riyals for 4-wheels (I live in KSA)

Definitely safe to do.

Definitely safe to do.

Btw do you have any idea how can one check the rim quality as these are not the original rims they're...Emm you can say replica AAA quality, so what should be checked before buying em? :\
