Hello, I found out today (late, but still), that with my current winter tyre set (205/55 R16 91H) three tyres come from Slovakia and one from Romania. I came up with this because I look at the things more closely as usual when changing tyres, and I noticed that three still have 6.5-7mm profile, one only 5mm. All four were bought at the same time in November 2013 at the dealer. The set has about 30,000km down. The with the 5mm is the Romanian tire. Fr age: Is the problem with the different tires at Conti or with my tyre dealer? I conclude from this that Conti has a problem with the quality of its Eastern European plants. Did Conti write that they should take a stand on the problem. What does your tyre experts think about it? Achja: Auto is a purely long-haul Audi A6 from 2003, 180hp diesel front scratcher.

Hello, I have read that the rim or tyre size affects the wheel diameter and thus the ground clearance of the car. I do not know how to calculate this. So e.g.: 235/55 R18 means Q = 235 = tyre cross-section in mm V = 55 = ratio tyre height to tyre width in % Z = 18 = 18 inches diameter (equivalent to x 2.54 = 45.72 cm) From these values one must now be able to determine the diameter or the half-meter in order to compare how much higher or more lower a car stands on the road if it uses this or that tire size. That is certainly quite easy to determine if you know it. Does anyone know it ? Thanks rapper PS: I tried the following formula – true the ? diameter = (Q*V/100)*2) + (Z*2.54)*10) With this formula I would get with the above mentioned tires / rim size 235/55 R 18 to a diameter of 715,7 mm With a tyre / rim size of 205/60 R16 I would get to diameter = 652,4 mm

Hello, the Somme is soon at the door and today the new rims have been ordered It is about 8.5Jx20 ET 45. With the tires I thought about the Goodyear Eagle F1 Asymmetric 2 XL FP in 245/30 R20 in 90Y (600kg should be enough with the 2.0 TDI 143PS, right?). I am still unsure about the wheel widths. I thought about 15mm per wheel and wanted to use H&R, have not found a suitable set with bolts yet. Do you think I get the combo registered this way? Greetings A lex

Hi guys, with my season car I will now upgrade to 18″ aluminium wheels and still need summer tires. I have seen/read the new test reports, but am still unsure. Around 225/40R18 should be mounted. Vehicle is a 3 Series BMW (E36) limousine. Ride in the season (04-09) max. 6tkm, only in nice weather, cruise more than I race. On the highway, however, more times are blown free. I calculated a lot and the Hankook S1 Evo2 would cost me about 420€, since against the better rated Barum Bavuris 2 ca. 348€. The absolute test winner Conti Sport Contact 5 ca. 490€. The Dunlop Sport Maxx RT, Goodyear Eagle F1 Asymmetric 2, Michelin Pilot 3, Bridgestone Potenza S001 lies between 440-480€. So price difference between the best is just between 70-140€. How was the Nexen N8000 tested? There would cost four tyres just about 280€. Which tire would you recommend to me with my vehicle, mileage in the year and driving style? Thanks and Greetings Patrick

Moin Moin dear forum! I just looked at my tyres in front and I noticed that I have such a wave-like line around the edge of the profile. Like the border between flank and tread. http://i908.photobucket.com/albums/ac281/connectab/adb74543.jpg I don’t have that much on all four tyres just at the back. Tires are Pirelli PZero Nero in 245/30 20″ Thanks already.

Hello to each other, a few months ago I had bought my desired rims + tyres, which I would like to raise in the next week and if necessary already drive. I had always only OEM rims + the tire dimensions on it, which are in the vehicle license. To buy I had already made myself smart, whether I can drive the rims at all and which tyres up. So far I had set myself on a single acceptance but now I am somewhat irritated, if this really necessary vehicle: BMW E39 523i saloon from 12/98 – keys 0005 567 – no modifications / original condition / no special entries rims: MAM B1 8×19 front and 9.5×19 rear tires: 235/35/19 front and 255/30/19 rear From the manufacturer MAM there is a part report for this combination in which also the mentioned tire dimensions are listed. See here for the 8 and 9.5 separate ABE documents. See here for the 9.5×19 And for both rims there are also separate documen See here I would have said now that on the basis of the documents no individual acceptance is necessary. Since for the combinations parts reports are available, could only a registration be necessary or am I wrong?

Hello, I have a curious problem: when changing tyres in summer -> Winter tyres I solved all the wheel nuts. But I still didn’t get the tire off! It was like baking it! Everything pulled and (one side) didn’t help. Did someone give me good advice on how to get on with it? Is there something like lubricant that I can use to work with the rim/axis? In general: how can a rim make itself so tight? Thank you! koasa

Good day, I would like to have a somewhat “remarkable” question. I have to add new rims and new tires next summer, because at the moment I drive on 225/45 R17 7×17 ET47. My new planned wheel-tire combination would be 245/35 ZR18 8×18 ET40, on which I would also let my speedometer calibrate, as it otherwise indicates too little (0.9 km/h, to be exact). The speedometer is known to be up to 10 % or 4 km/h too much but no km/h too little. With the help of a “Rei I could find out that the change in the outer edge of the wheel + 20 mm and the change in the inner edge of the wheel + 6 mm would be (see pictures). Consequently, the width of the entire wheel increases by + 26 mm. Now I could theoretically go and measure whether my intended wheel fits into my wheel box. However, since this is too inaccurate for me, my consideration was that I simply because the change in the outer edge of the wheel to my current wheel tyre combination was just I would be happy if someone had already had some experience with this and if this really corresponded with the new wheel in hindsight or if this really fit. Greetings Ravennwest PS: The + 6 mm at the inner edge of the wheel are no problem, because there is still enough space there. PPS: The future wheel is even 3 mm in diameter smaller (roll-off circumference – 0.9%).

Hello municipality I have been offered 4 new Pirelli Zero Nero from 2006 (5 years old) at a fair price! Are the tires produced just as well as currently? Do you have any disadvantages with such tires? What do you think about it? Ciao

Hello, would like to try it yourself and bring my rims on high gloss and fix curb scratchers. I would like to ask the forum for experiences and tips on how to do the best and which mediums are good and which should not be purchased. I just want to grind the scratches and make them smooth where necessary with such a paste damage. I will pass the painting on to a paint shop. Felge looks like this:http://www.hood.de/img/full/2135/213553 186.jpg This is not mine but has similar damage on the edges. I’m only concerned with the edge. The rest still looks top.
