Force Racing do split rim 6.5"x12" rims.http://www.force-rac...modular-wheels/
no cheaper I'm afraid but quality costs.
Only other option is 12" banded steel wheels maybe or Quad / ATV wheels but that is controversial and has been discussed on here before.
As for the tyre stretch, there are quite a few people doing this so it seems acceptable to them but whether its acceptable to you or even legal in BC and you want to try it only you can decide. Sorry not much help on that 
Thanks for the feedback Furyan.
I wouldn't be comfortable with a an atv wheel on a car. In my searches here for wheel and tyre choices, I saw that some were using golf cart and atv tires just to get the right tire size. Wouldn't want to go down that road,......literally, pun intended.
Good to know that there's people doing the stretch with success then. Haven't even thought of legalities of that. Wasn't aware there may be any. Guess I'd better look at that aspect also.
There are no cast wheels in that size so you would be going for a custom made 3 or 2 piece set up. Then you would still have the same problem you are stuck with the same tyre sizes so you won’t have anything wider than a 165/70 12 (or whatever size it is).
Right. Never thought about that. Kinda limited in tyre widths for 12's. Seems to be more available for 13's for different widths. Blimey! It keeps coming back to that. Wider 13 wheels. Wider 13 tires. It's like they're taunting me to the dark side.
Thanks for the tip.
Pricey little suckers, but pretty sweet. Good to know that there's still a 10x7 out there to choose from.
Ideally though, I'm aimed more to see if there's 12x7 choices out there to start. If not, I'll make the switch to 10x7's.
How much good or bad luck have people been having stretching a 165 tire on a 7" inch wheel though? How would it react to some hard cornering? Anyone experience a tyre popping off when stetched like that?
I don't plan to use it as a track car, but I tend to pretend that I'm in a go-kart sometimes on the streets.
As others have said, there are no 12x7 or 10x7 1 piece cast wheels, but Force Racing, Image Wheels, or Specialist components will make 3 piece split rims in any size you want, so that's not a problem.
As for tyre choice, the 165 will be absolutely fine on a 7" wide wheel. You will probably hear a fair bit of scaremongering telling you otherwise, but it's perfectly safe. It won't be the ideal setup for hard driving, as the tyre wall won't have quite as much flex, but as far as stretch is concerned, it will be fairly minimal, and you will run absolutely no risk at all of the tyre popping off, this only ever happens when the amount of stretch is extreme. I've been running a 175/50/13 on my 13x8" wheels for a very long time, and covered thousands of miles with absolutely zero problems.
I am very involved in the general modified car scene, so I see all sorts of modifications. I have seen 165 tyres stretched onto wheels as wide as 8" or 9" with no issues (not that I would ever do this myself!!!). Obviously stretch to this level will effect the handling, but still the risk of a tyre popping off is very minimal.
Thanks Chris for the recommendations. Looked up the other wheel shops there and found some contenders. Anyone have any of those? How are they holding up? Any pros and cons? Gonna hurt the bank account. This is where currency conversion really sucks. Those wheels, plus VAT and shipping overseas. Yikes.
Maybe what I could do is a 12x6 on the fronts and 12x7 on the rears. That way the fronts won't be subject to too much sidewall force when driven hard and in the fast corners, on an already stretched tire and rim combo. Also, the rear 12x7's may be good in the way of the wheel and tyre combo sticking out further to be flush with the outer edge of the arches. As it seems the rears suffer by being sucked inward and under the sport pack arches too much.
Wow. I'd be anxious about stretching a 165 on a 8" or 9" wheel. That's ballsy.
But if there's no major issue with the 165 stretch on a 7", that's good to know. Maybe I'll do that on the rears.
Thanks for the feedback. Good to know what's current now, after sorting through all the old posts with wheels and tyres that don't exist anymore.
