[chook69]

hi guys!
what is the best rim size an tire size that i can put on my 1991 VN.. ( i am going to lower it) the tires on it now say there R15s an there a skinny tire.. the tire guid that goes on the frunt near the radiater is missing.. so can i get a new tire guid to replace the old one?

nah legally you can only go 2" higher then what is recommended

It's Tyre btw.

You should be able to fit 18's without much of a hassle

Depends what you mean by 'best' rim size. If by that you mean how big can you go then you could probably get up to 20 or 21's, you would just need to roll back your rear guard a bit depending on how wide you go. But in my opinion the best size of rim and tyre to go would be a 17 or an 18. Just whatever you do make sure you get a tyre size thats similar in total diameter than your current stockos, there are lots of calculations available if you just search google. The one tyre size I know that is very close (like within 2 percent of stock) is 235/45 on a 17 inch rim. Otherwise if you get tyre sizes that are really different in total diameter then your speedometer will become inaccurate

Oh and with the wheel guard i'd say they're probably not available from holden anymore, so you'd just have to go to the wreckers and get an old second hand one

That's not actually true. There is no such rule that limits rim diameter.

My advice would be to fit a nice set of 19's with 235/35R19 tyres. The rolling diameter is perfect, the width isn't a problem and they are perfectly legal.

hi guys!
so what is the recommended size? an ill go up 1 or 2 sizers from that..im looking to put low profile tires on it aswell, maybe 205/40 or somethink like that, then i will be lowering it soon after

[zskinner]

if you only want a tyre thats 205 mm wide you probably wont be able to get any bigger than a 16 or maybe a 17 inch rim. even then a normal 16 inch rim will usually need about a 215-225 mm wide tyre. im sure you could find a larger rim that is still very thin for skinnier tyres but i would imagine they would be hard to find and pretty expensive, but i might be wrong, maybe someone can correct me.............

u can get a 205 18in tyre but the load rating would be way off wrong and handling and stopping would be reduced

im hopeless at stuff like this now, i use to be good once with things like this.. i cant remember what i did to my old holden when i was a youngster= the age must be kicking in lol, but anyway ill go for the rims 1st. i get a size 17 rim i think! that way ill have to put a nice low compound tire on there an thay will sit nicely under the gaurds (frunt & back) wen i lower it.. but haw far do i go with the lowing, the lowing part might be in another post, so i have look. if not i will talk about that on here

thanx guys!
your all champs

thanx zskinner! just found a nice set of 17s (Quest) maybe put 235/45 tire on them... so now can i get sloted rotors for the vn an what brake upgraids can i get?
im doing the wheel section 1st then put a nice lukey performance exhaust system with cat an headers in.. then work on the body section
