As some of you might have read my other post about "New Tires - ABS Problems" I recently bought a new set of tires for the G. Each tire was stamped correctly, 225/45R18 and 245/45R18. After I got the new tires, my ABS was activating at every stop as if I were on ice. I took the car to the dealership to have the ECU flashed, except mine didnt need an update. They then proceeded to check all my wheel sensors, which were fine. They took my car on a road test and hooked up a unit to measure the speed of my wheels, when they found that my front wheels were spinning 3km/h faster than my rear wheels. We then measured the diameter of my rear tires compared to one on the lot, and wouldn't you know it, my rear is more like a 245/50 rather than a 245/45. I guess this is what happens when you buy cheap tires that arent manufactured to spec.

I have to get new tires today :S.

DON'T DO IT.

Sorry you had to learn the hard way.

For the record, the inexpensive tires that have got HUGELY GOOD reviews by many Corvette, Porsche, and Nissan/Infiniti guys..
1. Kumo Ecsta
2. General UHP
3. Sumitomo
4. BFGoodrich KDW2

Also, you NEED to check the date code on the tires. Old tires become hard. Some places like Discount tire will sell you tires that have been on a shelf for 2 or 3 years.

For those reading this thread and don't know how to read tire age, it is on the side of the tire in the form XXYY where XX is the week number the tire was produced and YY is the year. For example, on this tire shown below, the tires are 2607... tires was made in the 26th week of 2007.
