    Thread: What are the widest tires you can use on MKV Rabbit/GTI?

    1. 10-09-2011 08:27 PM #1
      I dug through the Wheel/tire thread in the technical forums. That was mildly unhelpful. I found DAN GSR's thread, but I want to know how wide you can take it without altering camber.

      17x8 ET 45 - Possibly running 5mm spacers in the front if the wheels will not clear my new brakes.

      KSport Coils - With the minimum amount of drop - about 1 1/2 inches

      I'd like to stay within factory camber specs, the extra width is just for additional traction.

      Any help is appreciated.

      widest I have seen are 255/35 on an 18x8.5 rim- Dan Gsr's, but I think he had camber plates.
      I have 245/35 on 18x8.5 et45. I am not low by any means- 1.5" all around. I would choose 245/35, or 235/40 if you want a bigger sidewall.

      Thanks for the info.

      I'm looking for more of a contact patch for better traction. The KSports luckily have camber plates so I can adjust that. But I'm also concerned with uneven wear, which is why I'm trying to keep it within or as close to factory specs as possible.

      245/35 is probably best then.

      Looks like they either dont make or dont stock a 245/35/17 on tirerack.

      245/40 it is then.

      yeah, you are right about the sizes. What are you going with? i like the hankook v12's.

      I dont like the wheels on this car, but here's what the tires will look like in that size. I think we are one of the few who dont stretch

      Currently I have 225/45/17 Continental Extreme Contact DW's, they've been excellent for me so far and for being a Max Performance Summer tire their tread wear rating is pretty high 340, AAA. I'm stationed in North Carolina right now, and I have not had any snow/wet traction issues. Since I'll most likely be getting sent to the middle of the desert in California I'll be sticking with the Continental Extreme Contact DW's.

      These pictures are old and I'm still rocking Eibach Springs on Koni FSD's



      Whenever they decide to let us leave Afghanistan I'll put the coils and new tires on. With 250whp on 225's I can spin 1st and 2nd. 3rd will chirp but grabs almost immediately. My spare motor is sitting with C2motorsports right now having forged rods/pistons and a couple of other goodies thrown on. Shooting for around 400-450whp so I think the added contact patch will be necessary.

      Sounds like you have it pretty much sorted, but you might have better luck on golf mkv.com forum or in the motorsport/track forums here on vortex. Wide tires are kinda the minority here.

      You mentioned spacers... that 5mm can be a pretty big factor. So is ride height. If you are any lower than the cars posted above 225 45 is biggest you can go.

      So is camber spec. You need to settle these variables before you decide on tire size. You should be ok running about 2* camber as long as toe is good and you rotate tires like you should anyways.

      Well even with the coils I have to keep it fairly high. The turbo is too close to the drive shaft to make me want to chance going low. Highest setting for the coils is supposed to be around a 1.5 inch drop. That is close enough to what I have now that I'm not too worried, but at the same time I could be a complete idiot and find out it will not work when I'm putting it back together.

      I just found out that I am wrong and my wheels are 17x7. So I'm looking to offload those and grab a set of 18x8.5. If I need to adjust the camber than so be it. But I would much rather have factory specs if I'm dropping more than $500 in tires.

      The good thing about the 18x8.5 is that I would not need to run the spacers to clear the brakes. So that would put me back at the Et 45 and should allow me to run the 245/35's, I think.....

      then you will be fine to run 245/35 on the 18's. You definitely want to do the fender screw mod, and you can probably go 3/4's of an inch lower without having to roll/pull fenders.

      I would look for an 8 rather than 8.5. An 8.5 et45 will sit you closer to the fender of course. You'll be good at the height you're at with an 18x8 et45 easily and can fit more tire. I'd opt for a 255/40/18 to stay as close to factory specs (diameter) to keep your speedo as accurate as possible, and give you some more beef .

      DanGSR put 255/35/18's on his 18x8.5 and had to get a spacer to clear the strut. I think you'd be fine at 18x8 et45. If you rub under tight corners, set the dampers all the way to 36 and if needed, order stiffer springs from Ksport

      I just picked up a set of Enkei Fujin's that are 18x8 et45 and weigh in at 19 lbs on the nose. Best Craigslist buy ever, but they're under $1k brand new as well

      If I can find a set of wheels I actually like in 18x8 I would jump on it.

      Spent several hours looking yesterday and no luck. Seems the 18x8.5 is the only offering in the styles I like.

      Looks like I'll be rolling with a 17x8 and 245/40. I worked the math out and it didn't really make sense to grab an 18x8.5. Around $40 more per tire for 18's. Plus I just happened to run across a set of 17x8 that made my gentlemen vegetables rustle.

      Not to mention the additional unsprung weight from the 18's.

      Thanks again for all the help.

      You're better off with a 245/35/17. It's closer to stock diameter and the slightly smaller sidewall will give you more clearance from rubbing...but you may still want to kick that camber in if it rubs.

      What additional unsprung weight? How much do the 17s weigh? If you have no specific 18 to compare weight...what additional unsprung weight are you referring to? My 18s are 19 lbs, I would say you'd be hard pressed to find a set of cast 17s that weigh less than that.

      Also, unsprung weight is overrated of course. I've read all about it and looked at both sides of the "theory" and "real world results". Honestly, there's a small noticeable difference going from 30lb-18s to 19lb-18s. That's 11 pounds per corner, more than you're typically going to get going from a stock wheel to a lightweight wheel, and it is noticeable, but nothing major.

      He's right, first Google search result:

      http://www.golfmkv.com/forums/showthread.php?t=78846

      With pics...

      Says -3.2 camber in front and -2.6 in rear.

      The 18's I was looking at were VMR at about 23lbs each, the 17x7's I currently have are right at 17lbs each. The ones I'm looking at are 19lbs.

      When I'm running the specs i'm coming out with the 245/40's being 1% off the 245/35's are almost 5% off.

      I'm not low by any means so I dont think I'll have to worry about rubbing. If I need to adjust the camber I will when it comes down to it.

      You're right, I must've goofed up on the calculator. A 255/40 is actually a lot closer than 1% though haha. Do it

      Rubbing is not necessarily about being "low". The stock ksport springs aren't the stiffest and if you really dig into corners with bumps, there's a chance. I don't think dangsr ran camber plates on his setup just to get better grip...I may be wrong but I think he had slight fitment issues. Just giving you food for thought, your call

      Yeah I read through his thread about fitting 255's and it suggested that he had to adjust the camber to get the tires to fit.

      Luckily the coils that I bought have camber plates and I will adjust them if necessary. If I get really desperate I will follow C2's lead and cut the fenders and run flares for clearance.

      Thanks again for all the help.

      Please let us know how it turns out. Theres been a lot of discussion and theory on this and very little real world accounts from experience.
