While I only have 18K miles on my 09 SRX I too thought about going with FOUR 255/55-18's to allow rotation. Seems the 255's on all four corners is a natural. You'd just need to remember the TPMS will be out of wack.Caper10,
I just dropped 4 KUMO's from Tirerack on my '04 SRX. I decided to go with the 255's all the way around. Nicer stace than the skinny up front look. Besides it helps with rotation and if you do catch a flat you can use a full spare 255. I picked up a spare 18 caddy rim from Ebay. Doesn't match but its 18' and I never worry about flats on the highway with that donut. I love these tires and they were only $121 ea $53 shipping for 2 day ground. 255/55R18. Smooth and quiet. Best of all they protect the rims from curb rash.
I replace Michelin on my Acura cars after 20,000 miles or less and both Japanese replacements had a better and more quiet ride and were 1/3 the price.You get what you pay for.......lemme know when you get 62K miles oughta the Hankooks.
I still haven't decided on tires...still researching. I have winter tires on now and don't need a tire good in snow.Looking for something good in the wet and quiet. Some reviews I read say the Toyos are noisy..are they??? I am going to run the 255 60 17s all around. Local tire dealers don't have much of a selection and want too much for what they can get. But gonna have to get something soon...The choices are a bit weak in 17"
You do get what you pay for most of the time but not always.
Do you need an all season tire or will you be using winter tires?
They look to be a great alternative when the time comes to buy new tires but it appears they don't come in the Sport Option size (255/55-18). Bummer one less choice.The General Altimax HPs are very good in the rain and very quiet on my BMW. For the price, I don't think you can beat them!
