Subiect: Palmă cu piston: Cauciuc ars Sienna?

Mike scrie: Duminica,
Heres a hot topic for you and the B&B. I have a 2006 Sienna LE (front wheel drive) that has been absolutely bulletproof and reliable for the past 140k miles, except for the tires. I run all seasons in the summer and winter tires on separate wheels in the winter. We drive about 10k miles in the summer and another 5-7k in the winter. We live in the Finger Lakes region of NY.
Acest lucru mănâncă orice anvelopa care am pus pe ea.
I just took a pair of Cooper CS4s off the front that have less than 11k miles on them and they are completely worn out. I can get three seasons out of a set of 4 winter tires but the summers never last more than one season on the front. I get 20k or so miles from a set of 4. The alignment is good and the wear is very even. Rotating the tires nu-t change the tire wear, it just delays it. Almost all of the wear lucru se întâmplă when the tire is on the front.
Ive run Firestone FR710, Yokohama Avid Touring, Dunlop SP, Cooper Lifeliner; and Cooper CS4. They are all load index 98. Granted these arent the most expensive tire off the rack but do the ultra expensive high mile tires really last that much longer? All of the tires that Ive purchased have a warranty of 60k miles or so. The CS4 is 80k.
It is a heavy vehicle (nothing mini about this van); my brother joked that maybe I should run LT tires on it. So Im wondering, should I switch to tires that are marketed for SUVs? Tires in the same size have a load index of 102 so maybe theyd handle the weight better and last longer? They also cost de 50% more; they will last 50% longer?
I know everyone has an opinion about tires, perhaps one from the B&B will be the nugget Im looking for.
mulţumesc

La naiba, dacă meu lb 3200-ish Ford Ranger a LT anvelope (care purta ca fier, încă în căutarea de noi dupa 20.000 km) de ce nu le-a pus pe un minivan care cantareste 1000 + lbs mai mult??? În cazul în care vă sunt de remorcare, transporta o mulţime de marfă, etc. atunci probabil LT anvelope sunt o idee bună.
I poked around TireRack.com and found LTs for both the 16" sau 17" applications for similar amounts of cash as their passenger car brethren.
But one question remains: tire pressure. Are you inflating to owners manual specifications? Have you always used the same gauge? Are you 100% sure that gauge is still accurate? I learned to not trust old gauges the hard way when a bad voltmeter (20+ years old and the alternator problems with Fords (and lifetime warranty parts) from the 1990s ganged up to lie to me in a most convincing way.
Then again, Ive fallen for dumber, far more obvious lies. My easily malleable life aside–and even with TPMS in mind–could this be the problem?
Buy a new gauge, the cheap ones (with the super handy magnetic end) at the service of counter Wal-Mart/Autozone will suffice. If the gauges arent lying, then get some LT tires.
Off la tine, cele mai bune şi mai străluciţi.

This thing eats any tire that I put on it.

Hell, if my 3200-ish lb Ford Ranger has LT tires (that wear like iron, still looking new after 20,000 miles) why not put them on a minivan that weighs 1000+lbs more??? If you are towing, carry a lot of cargo, etc. then perhaps LT tires are a good idea.

Off to you, Best and Brightest.
