    Wheel/tire opinions - 5x112 issues

    I'm seriously looking in to race wheels for the GTI. The original plan was to go with 5x114.3 16x7.5 wheels and use offset wheel bolts to adapt to the 5x112 VW pattern. But, no one is selling the offset bots anymore ... at least not for an affordable price.

    So, I've written one of my wheel contacts that's in with Rota to see if they ever made a 16x7.5 with a 112 pattern. Waiting to hear back. I know they make 7.5" wheels and I know they make 5x112 wheels ... just haven't seen them together.

    So, here is the question ...

    No one really makes 16x7.5 wheels for the VW/Audi pattern. I can get 16's, but in a 7" width, or stick with 17's and get the 7.5" width I want.

    In the 16", I'd run 225/50/16 tires ... a common size. In the 17, I could run a 225/45/17 (stock) or a 245/40/17, but they are at least $20 more per tire. The 17's would probably weight more and move the rotating mass further from the hub, affecting acceleration.

    If I can't get a 16"x7.5" wheel in the 112, what would you guys do?

    a 50 series sidewall is going to be flex city.

    You can probably find some wobble bolts on vortex classifieds. I'll post up a wanted for you and see if I get any hits.

    I'll sell you the 17'' portos that came with the TDI .


    What's your ideal weight on 17's?

    edit: a quick search for wobble bolts in the wheel/tire classifieds popped up

      I still don't know if the even fit the wheels I'm looking to get. Might be worth checking though. Thanks.

      And ideal weight on a 17 ... 3lb. =) The lighter, the better. The 17's on the Evo are 17.3lb I think.

      I know a 50 series isn't ideal, but there aren't many performance sizes for a 16x7.5 wheel.

        Oh, and have you seen any threads on failures of the "wobble" bolts? I've never seen any, but would like to know if others have before going that route. For $50 I'll go that route easily as I know I can get the wheels I want in 5x114.3.

          I've yet to see one, they're certified by the DOT and some other body, so they must be safe-ish.

          I think the big thing is, you have to run hubcentric wheels, or else there is a chance that there will be stress on the bolts (since that's how vw's were designed) if the wheel is not hubcentric.

          Unless you plan on putting rcomps on them, I doubt you will have any issues.

            The Slipstreams are hubcentric and I can get the correct rings for them. I'm hoping that hubcentric wheels have a slightly larger opening for the bolt so I can use these. Rod is going to measure Zac's wheels for me and get me the specs.

              make sure the seat is correct as well. VW ran conical seats on some cars, and a tapered seat on others.

                Aftermarkets will be tapered.

                  Spoken like a true VW owner.

                  A 225/50 on 16x7 would work fine. Approved range is 6"-8" (if you're one of the people who even bothers to pay attention to that) and you're not trying to win a national championship on these tires. Save the money for an additional out of town autocross trip, and enjoy the rotational & unsprung weight savings as a bonus.

                    None of the 7.5" wheels are in stock at Rota anyway. If none are there by next month we might just go with the 16x6" wheels. At a +45 they will at least be lighter and give her a wider stance.

                      After looking around Vortex and some vendors today, it sounds like "tapered" and "conical" are used interchangeably. I know the ones you mean though ... VW uses a weird rounded seat on OE wheels. But, wobble bolts listes as both "tapered" and "conical" seem to have the same profile that's common to aftermarket wheels.

                        I remember making the bolt pattern on some 4x108 Mustang wheels fit the odd Mazda 4x110 by dremmeling the holes slightly to get them to fit. They worked well. It was 1mm per lug. Should be about the same for the 5x112 to 5x114.3.

                        A 225/50-16 Hankook RS3 at $104ea from Tire Rack on anything 16x6-16x8 should work well. I run 245/45-16s on a 16x7 with no problems...

                          Clay, the holes can be stretched, but the lug seat would not match. That's why I'm getting the "Wobble Bolts." Essentially, they have a rotating, offset collar with the tapered seat that can shift the pattern +/- 2mm. Basically, the are eccentric bolts just like those used in suspension ... jsut a different implementation.
