What tire pressures to use for stock 13" all seasons (my prev yota celica used 34psi front, 32psi rear)
I'm not sure which size you mean for stock, DLX models were supposed to run 155R13s, and the SR5 models were supposed to run 175/70-13s.
I run SR5 (the white ones, not the silver ones) rims on all of mine with 175/70 13 studded snows in the winter. With all of the canyon driving that I do in them, I run 32psi front and rear, otherwise i wear the shoulders and studs off of them. I rotate the studs mid-season for best wear, otherwise I get to spring and the fronts are worn down to nubbins and the rears look brand new. With the studs on them, I can run through over 2' of snow until the radiator gets too clogged with snow.

Sometimes even the cheapies can last over 70,000 miles with electronic ignition. My '86 Honda got 70k on the factory NGK plugs, I only changed them because I thought 70 k was enough on them, they were still running fine. My daughters' 01 Suzuki ran 114k on factory cheap NGK plugs by previous owner. who needs to spend $7 a plug when the $1.59 plug will do that?
Well they can. But with ignition systems, when the plug gap grows coil output increases. Todays coils throw a pretty mean spark. These coils have no problem finding an alternative ground when the gap gets out of spec. Could be a wire, cap, or the coil itself that starts leaking spark. Now you have a repair tuneup vs maintenance. I've had 2 of those this month, both tuned up less than a year ago. If the car came with them, that's what I put in. With some tuneups taking 3-4 hours or more now, the best plugs available are a no brainer. Some of the cheaper plugs have very little corrosion resistance too.
Of the few cars made in the last ten years that still run regular plugs, intervals can be as high as 60k or as low as 30k. BTW, a tercel is 30k.
On my T4, I do use the regular plugs but do them well ahead of schedule. I doubt too many of us don't consume a little oil or have a flawless carb if there is such a thing. Hard use shortens their life also. When I was a teenage road hazard, I did them every year and noticed improvement every time. With only 4 easy plugs on a T4, that's pretty painless.
I have to wonder about the Suzuki's previous owners maintenance schedule. Who needs plugs or fluid changes!
Obviously a group of people who drive 25 year old s***boxes don't need fancy plugs. Everyone else would like their tune up to last as long as the factory's.
Not trying to argue, but most people these days do actually need $7+ plugs. I didn't build it, buy it, or break it. But I do get to clean up the mess and am expected to do it properly.
