Really? At this level you think tires are an afterthought? You think all the Toyota automotive engineers and vehicle dynamicists went home early that day?
They chose a tire that met the design requirements. Simple as that.
Why would they put on a tire that
- has higher cost
- delivers a louder and harsher ride
- decreases precious MPG's
- contributes to heavier unsprung weight
to please less than 3% of the customers who buy the car?
To address this point by point (and yes, I still believe they totally blew the chance to make the "Trail Edition" a viable off road capable vehicle by putting street tires on it)
I'll use my load range "E" Bridgestone Revo II's as an example..
* I bet they could purchase both tires within a few dollars of each other
* The ride quality improved DRAMATICALLY by changing tires (now mine were Dunlops) no more feeling like you're riding on a ball at highway speeds and lane changing, or cornering at any speed. The traction differance was off the wall. (pulling a 2500lb. up a steep grassy slope, 4lo, locked rear, never slipped a wheel.....the spring before pulling the old 1500 lb. trailer up the same slope, same conditions, with the stockies, slipped like crazy but still got out, which I thought was no small feat)
*I lost 1 mpg overall..so I concede
* I do believe that's possible...especially if you go a few extra sizes up. If you stay within the same tire size as stock...maybe a few pounds?
I'm not sure exactly what 3% you mean...Trail owners or 4runner owners overall? The reason I bought the Trail was because of the attraction of being able to go off road in a bit more capable, trail worthy truck. The main purpose of my Trail is a tow vehicle(as well as a DD). If all I wanted was to stick to pavement, then I probably wouldv'e considered a Limited, and would have expected road tires. I just think there doesn't appear to be much thought put to the tire choice for the TE...whay hobble it with street tires? I think if you read the forums very often it appears the tires (and the horn) were the first things to go on many folks trucks.
