What Size Wheels Should I Get?

[bozodos]

the bogans giving you shit (ESPECIALLY with an N/A) might though I might go, if only to watch the complaining when everybody's dyno queen cars don't match up to their tuner's claimed power figures (usually due to the ambient temps being in the 30s and on a mobile dyno at that) hahaha.

Turk1 your wheels should either have a sticker on them or have the offset stamped onto them, there is a way to calculate offset, but I can't think of it off the top of my head

this is most easily done with no tyre on the rim and lying it on flat ground, but can be done with the tyre on, just have to change it slightly, but the general idea is:

you lie the rim on it's side with the face of the wheel up and measure from teh ground to the outside of the top lip of the rim, then divide that by 2. that gives you what zero offset will be. then measure from the ground to the back of the hub (the bit that contacts the hub of the brake rotor). now subtract the zero offset distance from the distance to the hub from the ground.

so for example if you measure the rims to be 178mm (7") that gives you a zero offset of 89mm. and if the distance from the ground to the back of the hub is 120mm, then you have a +31mm offset (120-89=31). if the distance from the ground to the hub is less than half you have a negative offset, but you still still subtract the zero offset distance from the hub measurement so that you know whether it is positive or negative.

personally i'm not a big fan of anything over 18" (even i see them as being bigger than needed). with a nice set of 17's they look good and don't spoil ride quality, and also have enough side wall so if you hit a pot hole you aren't going to stuff the rims up as easily. plus wheels get heavier as they get bigger.

as for tyres, just go something like a 235 wide. if you want to you could put a wider tyre on the rear, but i'm not really a fan. it isn't really worth it. sure it looks a bit cooler, but means that you can't simply rotate your tyres, or have to run different size wheels on the front of the car if you get a flat (since the spare is only a space saver). also it slows you down. sure having big tyres on the back will give you better traction off the line, but once you are up and moving all you are doing is adding extra weight and extra rolling resistance. and generally wider tyres are more expensive, so what you spend on a fat tyre you could buy a better quality skinnier tyre and have it give you just as much grip, but less rolling resistance, and have better grip in the wet.

Thanks for that brother! I'll have a look at it using your method and see what happens, I checked out my tyres again, currently sitting on 235/45R17...from the looks of it i got about 2 or so inches of dish. Probably will check out the offset tomorow and post it up, what your guesses haha lets see who gets the closest
