    Thread: 2018 tiguan: taller / beefier tires?

    1. 05-14-2020 11:07 PM #126
      Since I haven't seen any mention of speedometer calibration since the 1st or 2nd page of this thread I'm curious to know if anyone else recoded their speedometer with VCDS or OBD11? I chose option 6, which according to the measured values was expecting a tire size of 2323mm. This was the closest to what tires I chose vs how it came from the factory with option 3 which measured values showed as 2205mm. Several of the other options were not permissible even with security access enabled the system just wouldn't accept the coding changes. I then used GPS on both Android and iPhone to confirm speed vs actual speed under measured values (in kph from the VCDS) and they all checked out. I think I'm comfortable with trusting the speedometer readout now and calling it within less than 0.5% of actual speed. I did this at various speeds according to my local roads 25mph, 35mph, 45mph, 55mph, and 70mph and had my passenger track and record the speeds.

      Did you adjust "wheel circ" via obd11 in the instrument cluster module?

      Yes, then I used advanced Measuring values to see what the circumference was with each available option.
      Not every option was available even with security code access.

      Getting ready to join the beefy tire club in a few days and have a quick question for those with the Forge lift.

      I haven't bought the kit yet, but would you all recommend an alignment after the lift? I always get an alignment with new tires, but should I wait to mount them until I get the Forge kit installed to avoid having to have 2 alignments?

      Thanks!

      Just installed H&R lift springs and 255/55/18 tires . Slightly annoying the rear sits a tad lower . Can I just find a rear lift block to even out maybe? Or do the rear Atlas shocks ?

      Also I have 17s with Bf Goodrich in the wheels and tires forum if anyone interested.

      Looks great even without the riser block in the rear. Nice choice of W/T combo!

      Had the Coopers put on today (235s, def plenty of room with the spacers to go bigger though) along with 15/20mm spacers. Forge kit gets here tomorrow so I still have to install that, but loving the look so far.

      What 18” tires did you go with? The only A/T 18’s I can usually find are the Falken’s or Yokohama’s

      What is the lowest offset (or effective offset with spacers) someone has run with larger tires? I'm looking at the fifteen52 Traverse MX (17x8.0 ET20) and would like to run a 245/65R17 tire with the Forge lift.

      Any room for a 265/60/18? Or do you hit the strut?

      Curious, did you recalibrate the speedometer?

      If your speedometer reads
      65
      mph, you are going about 67.3 mph

      My Tiguan was lowered on APR coilovers, then my steering rack failed so I removed them. Now I’m waiting on a set of h&r raising springs, new 18in wheels and falken 255/55/18 tires. Should hopefully have everything in and installed next week. I hope no more random surprises with the stock suspension bits await.

      I've noticed not too many are running 18 or 19s, is there a particular reason or just wanted to stick with the 17? Since I'll realistically be driving most of the time around town or on the highway I don't want to go too aggressive an off road tire, but I would like the ability to hit the dirt when the time comes.

      I've seen that thread over and over very very few there have AT tires which is why I'm asking here for this specific scenario.

      Personally I wanted more sidewall in order to maintain ride comfort. The car is much smoother over rough concrete and gravel roads now compared to stock tires. Plus if you actually did do any off-roading that required airing down the taller tire offers more room for the tires to conform to the terrain.

      It obv saves some money as well staying with the stock wheels. If we lived somewhere with better access to trails I would consider going smaller with the wheels if they would still clear the brakes to get even more sidewall. For now they work great for our purposes.

      I don't think 18s would be horrible, but I've had a few cars with 19s and the ride quality decrease is pretty pronounced. It's why I've left the stock 17s on my MKVI Golf TDI.

      how close is TOO close to the lower spring perch? I fitted my 18x8.5 et40 wheels with 255/55/18 tires to the tiguan last night and damn its close! I ordered some 20mm spacers all around this morning.

      For day to day driving I don't see that being a clearance issue, however if you're doing any off road, mud or snow I could see that buildup could give you a hard time without spacers.

      BTW which tires did you mount?
