what does the tyre sizes mean 5 x 108 i know 5 means 5studs. but what is the 108 mean. also some say Et45 whats that :headvswal

The P.C.D bud!-if you drew a line thru' the bolt holes to form a circle then measure the diameter it gives 108! :)

Et (whatever) is the offset,either positive or negative.

And it's not the tyre size mate, it's the rims :D

HTH!

so what would et45 mean

ok im looking for some alloys but im having trouble finding some what is the best size for the zed im having eibach springs and kyb shocks fitted after. i was after 17 but have problems finding 235front and 255/265 rears. im not after spending huge money yet i have the wheels i want but much later
