| For my lease return, I need to replace just one tire. Infiniti wants $300 for the tire. Do I need to get the exact matching one, or can I have a different brand, but keep the same size and speed rating? If I did it that way, I would save $150, but 1 tire wouldn't match. HELP! 265 60 18R 109V | |

Hi: I've got the non-sport pkg 265/60 18's on my 06 FX35 and regretted not getting the sport pkg w/better handling/braking (and therefore better safety). 3 1/2 yrs later I decided to get lower profile tires, but as you may already know, there is no lower profile 265/55 or 265/50 in 18" wheel. You have to go down to 265/40 18, which do not have enough sidewall to carry the weight of our vehicles (from what I was told by tire rack). Despondent, I went to get the best Michelins (Lattitude Tour HP) in my stock size. After costco told me I'd have to wait a week to get them in on order (nobody stocks that size), I held off (gret price though (little over $1000 installed out the door after $70 rebate) and went to Radial Tire in Silver Spring, MD. They do all tires but specialize in higher end makes. I lucked out and spoke w/Paul, the owner who is always there, and told him my story. He did some math, looked up a few different makes, and came up with something amazing. Our stock 18" rims are 8" wide which can take up to a 285 - that's right - 285 tire. We didn' want to change the overall diameter of the tire on the wheel, and the closest thing to perfect was a 285/55 18 tire. I was skeptical at first because even though this combination is within 1-2 mm of the stock wheel/tire setup, and wouldn't rub the fender on straight ahead driving, I was concerned that the extra width of the tires (20mm wider means the tires are each extending 10mm to the left and 10mm more to the right) and might rub the fenders in extreme lock turns (turning steering wheel all the way left or right). He understood my concern, and reassured me that the setup would work. After explaining that I was leaving on Sat 11/21 for Thanksgiving up in NY, and that I needed the car to be right on Friday 11/20, he said he'd order a set of the Michelin Lattitudes in the stock 265/60 18 size just in case!!!! Wow! No tire dealer has ever volunteered to do something like that for me before. I must add that my existing tires were still the stock Bridgestones which came with the car when I bought it new from an Infiniti dealer in Bethesda, MD. After returning to the dealer the day after I bought the car (it had a nasty steering wheel vibration) we all thought it just needed a wheel rebalance. They promptly did one for all 4 wheels, but the vibration was still there (marginally diminished). The next thing they tried a week later was to rotate front to back, and that again marginally diminished the problem, but the vibration was still there. After speaking to other knowledgable tire people (and another Infiniti dealer) the concensus was a tire out of round. Putting the fronts on the rear of the car helped, which showed that the bad seed was one of the rears now, but the Bethesda dealer said to drive around for a few thousand miles and to see how it is then. I said it was likely a tire out of round, and they said that the tires weren't part of the warranty and they couldn't do anything more for me. This, for a $40K new car only a few weeks old. I felt like I had bought a Nissan instead of an Infiniti (from a customer service perspective). Having been given the runaround, I have since given all my business to an Ellicott City, MD Infiniti dealer, and the treat me like gold, and a road force balance they did confirmed my left rear tire was out of round, and they balanaced it as best as possible (the vibration was reduced further still (Bethesda Infiniti did not even bother to do the road force balance - to avoid confirming my claim about the out of round tire no doubt!!!!! Back to the good part - long story short, Paul he ordered the tires an they arrived Friday (both sets as promised). The285/55 18's (Pirelli Scorpion Zero V rated all seasons) fit perfectly, there's no fender rubbing anywhere, and after driving them home on the DC beltway yesterday, I have to say I love them!!!!! They were only marginally louder than the stock Bridgestones, they gripped better braked wayyyyyy better and responded better to quick lane changes (yes, I know any new tire will feel better than an old one, but driving the same roads with this car since new, I could recall how my car felt when new). And as an added bonus, my 3 1/2 yr old FX finally feels like a brand new car because the steering wheel has absolutely no shimmy or vibration - I couldn't be happier! And these sportier tires combined with the less harsh shocks of my non-sport pkg vehicle give me everything I wanted without the harshness (on bumpy/pothole ridden roads) for which sport pkg FX's are known. As an aside, the 285/55 18 Scorpions I got are the original equip tires for the previous generation Mercedes ML AMG!!! which is a much heavier vehicle than the FX. Good luck to you! Deannie |

My wife's 2005 FX 35 will need new tires soon. Great post Deannie, I also have had good service from Radial Tire of Silver Spring. Can I ask how much the all-season Pirelli's were? |

| Just had a set of Blizzaks put on my 2004 FX 35 with AWD and I now have steering wheel shimmy. I went back to the tire shop that mounted them (bought them from Tire Rack) and they rebalanced the fronts. The shimmy is still there but much less. Having said that, there should be no shimmy at all. Is this something I should have done at the dealer because of the fact you can't put weights on the outside of the wheels? Would they do the balance differently? Please let me know if you have experienced anything similar. | |
