  1. Couple of months ago had CEL come on for first time, and knew it was probably minor, but...

    Get diagnostic read-out of P-1125 both times, shut CEL off, then drive it a little hard or long distance and get light back on about every 150 miles or so. Need to get smogged and can't with CEL on, and would like to fix this issue.

    Any ideas? Intake filters? Sensor? Grounding Issue?

    '98 Boxter 74k miles. Thanx!

  2. After reading input on Michelin rubbers, have to agree with putting good rubber beneath you. Only comment on Khumo tires is that the sidewalls "racked" in semi-stiff rally driving, and I was glad it was not my car. I suppose they would be ok for to the store and back driving. Jay brought up good issue about where you live, and related weather, as determining factor.

    However, if Tire Rack testing indicates the Sumitomo htr III (not II's) have superior treadwear ratings, and 300 UFQC ratings while best Michelin is 220. After 5000-plus miles, I can see why they are rated highly, and I must admit to detouring to catch a windy road home.

    The primary concern placed on Sumitomo III's has to do with "wet" performance, although it still rates higher than most. It should be noted that "wet traction" testing is only done on straight-line, and with 5,000 miles under belt I can say they do nicely on often wet coast roads of Northern California.

    It would be interesting to see more lateral testing - the sidewall cross-rib construction is a primary reason I selected Sumitomo III over Michelin's transverse ribbing.

    Enough said, and enjoy your ride!

  3. hi,

    have had Sumitomo htr III for about 6 months and they drive better that Bridgestones, and really grip road when you step down.

    tire rack ranks them very highly, and mine cost less than half the price. located in northern california, and have recommended to series of people.

    enjoy them!!!
