What size rims

[vc commodore]

Thanks for your reply.The car is lowered with pedders low springs all round , these springs bring it down app 25/30 m. Unsure of offset, the ute is being used for work and does pull a trailer ,18s look ok , thought 19 would fill guard in a little more ,
I was looking at some second hand 19s on gumtree , didnt consider 20s thought they would restrict the ute , ute needs to go up steep driveways and gutters.
Whats your thoughts stay with 18 , or go 19 or 20 ,
Cheers Hank

Stick with 18" Pulling a trailer, kerb hopping and lovely bumpy roads you need sidewall in a tyre to help protect rims...19" and 20" with that combination is asking for stuffed tyres and rims...Tyre shops will love you, but your hip pocket won't love them
