Thought I'd share some info on 18" winter tires
For those who are considering 18" square set-ups for winter, I am posting the following dimensions of some sizes/brands of tires I researched on Tire Rack, and how they compare to the stock 19" tire sizes:
19" stock tires: Front: 245/35/19 Michelin PSS - 25.8" diameter, 807 revs/mile Rear: 265/35/19 Michelin PSS - 26.3" diameter, 790 revs/mile 18" square set-up for winter: Bridgestone Blizzak 245/40/18 - 26" diameter, 801 revs/mile, fits 8.0"-9.5" rim (diameter in between stock fronts and stock rears) Michelin X-Ice 235/45/18 - 26.3" diameter, 790 revs/mile, fits 7.5"-9.0" rim (matches stock rear diameter exactly) Michelin X-Ice 245/45/18 - 26.6" diameter, 780 revs/mile, fits 7.5"-9.0" rim (a bit bigger than stock rears, much bigger than stock fronts) Michelin X-Ice 245/40/18 - 25.7" diameter, 809 revs/mile, fits 8.0"-9.5" rim (smaller than stock fronts and much smaller than stock rears) I did not include 255 treadwidth tires, or winter performance tires, because I am looking for a narrower treadwidth winter tire that can handle the deep snow we get up here. Obviously this is a short list, but I figured I'd share it with you guys in case you find it useful. |

The only explanation I can think of is concern that the fronts will run into clearance issues since the stock front tires are slightly smaller than the stock rears, so the Blizzaks may be too big for the front... Maybe Keith can weigh in? Last edited by IS+1; 09-30-2016 at 03:37 PM.. |

I have used the Dunlop SP Winter Sport tires for many years. The dimensions are the same as the Michelin X-Ice, but the Dunlop's are speed rated for 149 mph vs 130 for the Michelin's. So on the dry days in winter you're limited to only 130 mph. LOL...
JK... I am just curious why TR pushes the Michelins? Mike

I lived in Malone, NY for 7 years, and drove my A6 sport and then RS6 with said tires for seven REAL north country Winters! Every other night call (more in the last two years) for 7 years, believe me, the road was often not plowed when I had to go in in the middle of the night. I had Blizzaks on my 97 M3 (lived in New Hampshire and then in Malone) and they were very good. But they were terrible on dry roads! SQUISHY. The Dunlop's handle on dry roads very nicely, and not as noisy as the Blizzaks! I drove my A8L in Binghamton for three winters with all season tires so you are correct on that count. Our prior Siena Minivan and now our Q7 also driven with all seasons. Both AWD of course LOL. Dunlops for me! I frequently drive over 130 mph in the winter. not really Mike

I still am hoping to have my RS back on the road for the winter driving.
My engine was out Oct to June this past year for an oil leak, ended up replacing a bunch of stuff but my mechanic talked me out of replacing THE TIME BOMB that he swore he replaced about 12k miles ago and 'checked'. Ended failing, lucky I did not loose the valves. You learn things that one should not have to learn The Hard Way. These car manufactures KNOW there are parts that will fail over 100000 miles, we know it is pricy to replace them but at least WARN us....Hot Oil, Fast moving chain, Metal on plastic, D'ooh.....

The Time bomb is the Cam Chain Tensioner, pictured above, the plastic guide wears down to the metal parts and then the metal chain cuts into the CCT, not good......

As for the size, any 245/40/18 would work. |

If you would like to build your own package, click the link below. You can then select 18" packages and build your own package by selecting the tire of your choice and the wheel of your choice.
http://www.tirerack.com/snow/WinterP...ModClar=&a=BS4 If you live in an area where you really need the absolute best winter traction, I would recommend a studless ice and snow tire, something like the Blizzak WS80: http://www.tirerack.com/tires/tires....age=true?a=BS4 or Michelin Xi3: http://www.tirerack.com/tires/tires....age=true?a=BS4 If you live in an area where the roads are typically clear, but need a winter tire for the bad days; I would go with a performance winter tire as these will handle best on dry roads. Two of the best - Pirelli Winter Sottozero 3: http://www.tirerack.com/tires/tires....age=true?a=BS4 or Michelin Pilot Alpin PA4: http://www.tirerack.com/tires/tires....age=true?a=BS4 |

To find the 18" wheels, follow these steps: 1. Click this link http://www.tirerack.com/snow/WinterP...ModClar=&a=BS4 2. Select build your own 18" package 3. It will first bring up the tires. Select the tire of your choice, click "add to package". (if you do not want to purchase tires, just select any one of them and then later remove from your cart) 4. Now it will bring up the 18" wheels. There are about 20 model to choose from. Once you select a wheel, add to cart. 5. Next it will ask you if you would like to add TPMS sensor and mount & balance. 6. Finally, you will be in the cart with your selections. (This is where you can delete the tires if you do not need tires) Last edited by Rudy@tirerack; 10-05-2016 at 09:15 AM.. |

Sorry about that. Somehow the link got corrupt.

Feel free to call me or email me directly if you have any questions. Thanks! Last edited by Rudy@tirerack; 10-05-2016 at 09:18 AM.. |
