Hey Guys,

So I just picked up a 89' yota two days ago. I finally got to drive it but it was raining today and completely scared the crap out of me. I drive a 5 spd and I don't think it's my driving that caused my tires to really slip. But, I do hear that when there is no load in the back, there's no weight to push down the back tires, I believe this, but how much of an affect does it have? Another thing I wanted to mention is that 3 of my tires are of the same size, except 1. The right rear tires width is 2 sizes smaller than all the rest. I just wanted to know if this one tire can really make that much of an affect on the handling. And hey, if you really think it is my driving, tell me whats up, I just want an answer or some help. -Anthony

 

Well, back when I had 2 dana 60's in the bed of my work truck, I would say it drove like a caddy and gripped like a dragster, minus the power. The smaller tire will cause uneven tire wear and yes, it will effect the handling since it makes it so that the rear axle doesn't sit parallel to the ground making you tires sit so that they're sitting in the edge.

 

the difference in width isn't a big deal. but a difference in diameter is. your tires may have a different diameter so one wheel is smaller. that wheel will break loose much quicker than the other and you'll 'spin out' frequently. this is similar to having a "donut" spare on.

you can use a tire calculator like this one:

to determine if the tires are indeed different diameters. if they are, i'd recommend rotating that smaller tire to the front axle.

also, make sure your tire pressures aren't maxxed out. air down to an appropriate pressure for an empty bed, and you'll gain some traction.

once you have same diameter tires, aired appropriately, you can then evaluate your driving and if your foot is just too heavy for an empty bed. throw in some sand bags or old tires for a little weight on the back end through the winter season. good luck!

 

Yes depending on when it last rained.

What kind of tires

and the odd ball size will give you grief .

Get used to it .
