Replacing with wider tires on stock rims.
Recently looked at my front tires and the inside and outside edges looks very worn compare to the center portion. Maybe a couple of thousand miles left. The rear are fine. Could it be low air pressure? I am running 37 PSI cold (early morning ambient temperature is about 72F),
Looking to replace with the new Michelin PS4S tires on stock rim. I am thinking of using 275/30R19 in the front and 295/30R19 in the rear. I would need to order online soon from tirerack.com as no one on Guam carries Michelin PS4S at the sizes I am looking for.
So I would appreciate any comments as to go with the size I stated. Just curious to know how many people have done this size increase on stock rims.

275/30/19 will fit fine on a 9" wheel, but will have .5" smaller OD than stock (25.5" vs 26"). Many folks with ISFs are running that size on the ISFs 9" rear wheel. 295/30/19 will also work well on a 10" wheel, but will have .6" smaller OD (26" vs 26.6"). So the stagger will remain the same. Your speedometer will be off a bit, and you will have a larger fender gap than stock.
I am running 295/30/19 Bridgestone S-04s on RCF wheels on the rear of my ISF.

Any other flaws with going with 35 aspect ratio?

I am running 265/35 and 285/35. Which means I am .3" larger diameter than stock. My speedo is nearly correct now (When it says 80 I'm really travelling about 79.6 instead of about 78, GPS verified). I would imagine that with .5" diameter bigger it would read a little bit over.
The only differences I noticed were a slightly softer feel in corners due to the taller sidewall, and I took about a 1 MPG hit while travelling at 80. However, since I replaced my rims with lighter rims, that MPG hit has been reversed into a MPG gain over the stock setup (not by much).
I can also hit 174 MPH now before the limiter stops me. It was ~171.5 MPH before. GPS verified.
I'm not recommending going that tall, nor am I saying not to do it. I'm only sharing my experience.

Just FYI - I went 295/30 275/30 on the OEM 19" rims which retains essentially the same stagger front to rear. This is a pretty small difference from the stock tires size in diameter, you can't see any difference in gap, etc. I'm happy with this setup, gives the wider look and no issues.

I haven't been back home in a little over a year but didn't see too many on the road then.
I'm flying home in April though so I'll keep a lookout.

Michelin Pilot Sport 4S arrived
Just received my Michelin Pilot Sport 4S from TireRack. Went with 295/30R19 for rear and 275/30R19 for front. The 295 looks massive and hopes it fits properly in the 10" wide stock wheels. Will get it install in a few days. TireRack rep made a comment that I went outside the recommended size for my vehicle before I placed the order. Hope I am not going to regret my purchase. Crossing my fingers and toes...
