hey guys looking for rims for my rolls and wondering what size is the largest and what width is the largest also I'm a but new so what is an offset and the benefits of one?

I saw someone recommend 195x50x15 6"Width

 

38-45mm offset

Youll need more offset to clear the strut. I have 205/50 15x7 +36 and I'm about 2mm away from the strut? I run 3mm spacers to space it out a touch more and still have about 8mm till i get to the guard. 6.5s will fit a bit nicer

There's a few more things to consider when changing your wheels. Larger wheels will probably weigh more, which weighs down your acceleration and steering. Also, if you put larger rims and tyres on, your speedo will be out and they will affect your fuel economy.

 

There are a few good charts out there (Google) which will make sure with a lower profile tyre you'll get the same rolling diameter, which will make sure the speedo isn't as much of an issue, but the FX-GT rims (GTI in Australia, I think) are actually pretty light so hard to beat. I used to have a set of standard rims with balding tyres, and they handled much better than my 16s with meaty tyres for (I assume) weight reasons. Accel took a hit, too - not ideal.

 

Have a bit of a hunt around, and talk to some tyre shops about their recommendations. Offset was the biggest thing for me here, I think ET+35 is the max the 'rolla can take (correct me if I'm wrong, guys). This is without spacers, anyway.

 

One more thing: with larger rims and a smaller side wall, you don't have as much travel in the side of the tyre. This makes it harder on the rims and suspension when going over bumps, and affects handling also. A friend of mine who worked at a tyre shop a number of years ago seemed to think 16" was the optimum size to go for in a smaller car for the reasons mentioned above, but bear in mind since fewer new cars are released with 16" rims as standard (you get heaps of 15" or 17") tyres are more expensive (because they're not as mass produced).

 

Hope this helps!

I effectively run 15x7 +33 for the track... needs more 5mm more poke for me to be happy as i need more room to add even more camber in the rear.

 

Ive seen an AE82 with 15x8 +25, just needs the guards rolled with minimal rubbing.

 

195/50/15 tyres are perfect size for an AE82 if youre going 15's. I run 205/50's and they are just a tad inaccurate but i can't find cheap track tyres in any other sizes that will fit.

 

Problem with the stocko stuff is that it wont clear aftermarket suspension, and you don't have any performance tyres in 14 inch...

 

 

My next set of wheels will be 15x7 (or 6.5) +25 to +30 depending what i can find if that gives you an indication. Perfect stance if you roll your guards and camber it a touch.

I'm running the sportivo corolla wheels and the offset is a little to high but they still fit with the right tires, they're heaps wide but i think they look good. I'm only running lowered king springs though.

6" isnt very wide... :P
