Even 31s are a little rough with stock gearing. You'd definitely love how it handles with 31s comparatively. Will look different though, cause of the lift.

I had 30x9.50s on my first gen and they were perfect for me.

 

What do you mean by a little rough? I've had 31s on both the 82s I've had with no issues.

 

Yeah, the 31's are in a sweet-spot. Fills up the wheel-wells well on the classics. Yet do not rub, even without a lift.

 

One of the biggest pluses about the older yotas over newer ones is the size. Toyota has gradually largened their trucks from minis to mid-sized. The 1st gen truck is just awesome in looks and function. The longer the wheel base the larger the tires need to be to clear the same obstacle. Bigger is not always better.

Sweet 1st gens!!!! 35's look just right!!!

 

Rough as in power-draining. I agree that 31s are the sweet spot for looks, but not for power. For me, 30s were the right compromise between power, looks and clearance, but I like the look of a skinner, not-so-big tire. I know I'm not in the majority 31s will get you there, power-wise. But 30s are even better. Obviously not for everyone, though.

 

I can't imagine noticing a huge difference between 30 and 31 inch tires. But I suppose there would be some. Especially 9.5 vs 10.5 width.

 

What do you prefer?
Short or long bed?
Gas or diesel?

 

So, if my drive train is totally stock, and I am currently running 33" BFG is it implies that I could be putting significant stress on entire drive train system leading to premature failure of some component? I know that the speedometer reads about ten miles per hour high and it is a bit more sluggish because of the power to get all of that rubber turning. My issue is that no one seems to carry a 31" BFG in stock so I can compare it next to the truck. I am leaning towards downsizing though and putting some new wheels on it. First though the other week I noticed some white smoke coming from the exhaust so now I’m dealing with that

 

 

Yep. And not surprising considering they're geared for 28s. I noticed a significant difference switching from 31s to 30s. Even on my 98. It came stock with 31s, but I always felt it was a little sluggish from a stop in first, so I decided to try smaller tires. 30x9.50s ride way different, with a lot more pep.

Probably not the right choice for a lot of people, but since I tow, having that low first gear really makes a difference.

It's all about the right gearing for the tire. Nothing wrong with 33s. Except that with stock gearing, they're power-robbing.

 

ive always liked the long bed. Ive had 2 now. And gas as ive never seen a diesel 1st gen in the states

 

Ok, so whats the correct gearing for 31s? 33s? Thinking about doing the same thing with mine

 

Oh there's a chart online somewhere. Honestly since buying my 98 I've just driven it (aside from the new tires) and started to forget all the "mod" information I used to think about all the time. 4.56 is the gearing for 31s. Not sure of any others (other than 4.10 being stock for most 80s/90s Toyotas).

I went through this with my truck...My axle code claims I have 4.10s. But my trucks speedometer is correct with 31s. So...Did someone change the speedo at the dealership to read correctly with 31s or something? Or is my axle code wrong? I don't know. I know I'm pushing higher-than-I'd-like rpm at highway speeds with 30s, but that the truck felt sluggish with 31s. Would suck for towing. And the speedo was definitely right with 31s and off a bit with the 30s.

Who knows. I'm happy with the 30s for now but not sure what I'll go with when they wear out.

 

figure your gear ratio out by counting pinion rotations with rear lifted. Open dif lift one tire locked dif lift both tires. Turn rear tire 2 times count pinion revolutions then divide by 2. Gear ratios are 4.10; 4.56; 4.88; 5.29; 5,71. Of course there is the 4.11 from older 8". Sometimes its hard to know whats in an old rig that has had multiple owners by pulling vins or color coding on dif.

 

[QUOTE=83;52394807]Oh there's a chart online somewhere.

I know, I saw it, but now I can't find it. I'm not sure where I saw the chart, weather it was here or another site. Anybody? I really hate when that happens.

 

 

Shouldn't the speedo run lower than your actual speed when you increase tire size?? Increased tire size = fewer rotations....no?
