Tamago's guide to ultimate yaris handling

[arnoldod]

Thanks for this great guide! :)

I had problem with handling in my first 4000 miles but now the handling has changed drastically. I do not do autocross. My driving characteristic is spirited driving, but only in the weekend. I am stuck in the traffic for the rest of the week with 19 Mph average speed.

I am using Toyo Proxes R1R 195/55/R15 with Advanti Storm-1 wheels (10.9 lbs). I understand that the tires won't last to 20,000 miles but my mileage is short (40 miles weekdays, 28 miles weekend).

The air pressure for both front and rear is 35. What is the recommended air pressure for my tires?

if you are commuting, and experience little rain, you could up that pressure for better fuel economy (provided the roads are dry). if it rains, keep the pressures at or slightly below the recommended pressure. remember too, your vehicle weight distribution. there's no reason to run the same pressures front and rear (if you don't carry many passengers, or heavy loads in the rear of your car) as your weight distribution f/r is at least 15/20 percent in the rear "less". less tire pressure in the rear will prevent oversteer, but also may induce understeer on sweeping turns.

as you aren't actually racing the car, all of the above is just theory. enjoy the yaris, and i'm sure tire pressures won't really be a factor. there's really no reason to ever push your car past 70% capability on the street, legally.
