I have had my 2005 Celica GT (automatic) for 2 weeks now, and after putting on 1500 miles, I thought it was time to test the car a little.
However, I got a surprise when I was pushing the car in a hairpin turn (uphill) - the car lost traction and skidded with screaming tires on dry pavement. Several other times only the rear end skidded. My car came stock with Bridgestone Potenza RE92 195/60/15 tires - could these be at fault?
My driving is a mix of highway (commute) and windy backroads (for fun). What would be good tires for my kind of driving? I live by the coast, so I don't need tires that can handle snow, but they should be able to handle wet pavement.
Now, over to other questions:
Does it matter what octane gasoline I use on the 1ZZ-FE engine? The handbook says 87 is ok, my dealer advices me to use 89 for regular use and 91 if I want to push my car.
Is there really any gain from CAI
/RAI on the GT's engine or is this overrated?
