What have you done with your trucks today

Since it was adjacent, I also inspected and cleaned up [w/ a wire brush] the ground srtap end from the Block to the Firewall. It wasn't bad but it's good to keep up.

Thursday I was going to help a friend troubleshoot the dead headlights on his '16 Subaru Forester. But I couldn't find the special Fuse Pliers I ordered off Amazon. So we cracked the beers early.
I looked again today, but I had put them somewhere ''safe''.

Barn Gremlins got them or they're hiding from you.

Get another one. The original will get jealous and show up. It's called tool Envy

No the Gremlins just put them in my briefcase, instead of the electrical tool bag. Sneaky Devils. Turned out my friend's Subaru had blown bulbs, like I suggested. He wouldn't let me pull a continuity check on his headlamps. Insisted they were new. Maybe they were, but still burned out. So he had the Dealer replace them. Hopefully under warranty.

Anyway, Today, I took the '03 'Hoe in to Discount Tire. The truck has a nasty shimmy/shudder above 60 MPH. I figured a balance and rotation would either eliminate that gripe or pinpoint it. Without moving it, the Tire Tech, showed me there was irregular wear on the Left Front, probably from bad alignment. That tire rated at 4 of 10. The other three were 6s. While rotating that tire to the rear, and getting an alignment at another shop would have been the No or Low Buck solution, I remembered I have a set of Cooper 235/75/R16 tires just sitting in the sunshine and gathering spiderwebs.

A couple of years ago, when gas was up to $5 a gallon, I decided to remove the 33x12.50x15 Falken meats from the GMC Jimmy, my only runner at the time. An old friend had taken off a set of aluminum rims from his new-to-him '99 Suburban. He thought they were too ''bling-ey''. He gave them to me. I got 2 pair of 2'' aluminum spacers and had them mounted on the Jimmy. They ran fine. My speedo was true, according to the GPS, They handled very well in city traffic.
But one rainy day I was on the freeway to see an old college buddy, some 60 miles way, and weird vibrations at speed scared me. I got towed home. First I pulled the aluminum rims and put the old 33x12.50x15s back on. Bad vibes continued. I put the GMC up on jackstands, and rotated the propshafts. My Transfer Case had accidently slipped into 4 HI. I put it in 2 WD and it was better. But a U-Joint was AFU. When I was under to R&R it, I saw the Carden/Lloyd constant speed assembly on the Front Prop Shaft was FUBAR. So my 4WD Jimmy is currently a 2WD. A new Front Prop Shaft runs $500. I ogled the Front Prop Shaft still on my dormant '67 K/10 Suburban, looks near identical, but if I extract any more parts from old White Fang, she'll never rise again.
The result was I parked 4 good, expensive tires behind the Suburban for a couple years.
Tonight, I loaded them on the back of the '68 C/10 Stepside. Tomorrow, I'll drop them off at Discount Tires and they can mount them on the 'Hoe.
The rims should fit fine, since a '99 Suburban is the same platform as the 2003 Tahoe.
I measured the current tires on the 'Hoe: they were 29.5'' high. They are 265/70/R17s. The diameter on the Cooper 235/75/R16s is about 29'' but it's hard to read when not mounted on a vehicle. [Coincidentally, the height of the 33x12.50x15s is also 29-1/2''.]

If the diameter is radically different, will I have to get anything reprogrammed?

I took my 2003 Tahoe to the shop [Brake Masters] today for an alignment. Cost $100, but it shouldn't wobble at freeway speed now.

My attempt at putting four 235/75/R16s on this truck was a bust.
Discount Tires refused to swap them out with four 265/70/R17s. They said the Drivers Front was irregularly worn from bad alignment, and strongly hinted I should buy a new one. They rated that one at ''4'' [out of 10, I guess] and the other three at ''6''.

The 235/75/R16s were mounted on some aluminum rims a friend kicked off of his '99 GMC K/15 Suburban [before the Yukon XL name change]. I had them on my '71 GMC Jimmy with 2'' adapters. When I heard irregular noises I took them off and went back to 33x12.50xR15 tires. But they are 2022 Cooper tires with very little wear.

I figured a 2003 C/15 Tahoe was about the same platform as the '99 Sub.
The tire expert at Discount said the set-back was different on the rims, and also the 235/75/R16 tires were rated at 1008, but the 265/70/R17s were rated at 1111. [What ever that was.] I still think they were trying to upsell me another tire.

The guy at Brake Masters said to go to another tire shop he recommended and they would probably put the Coopers on my Tahoe, since I'm not likely to be zooming around above 100 MPH, ever.
In the meantime, they put the ''4'' tire over on the Passenger side, so it'll even out the wear.

I finally got around to buffing and waxing my 99. I still need to paint the roof and hood. 4.3 V-6, 5-speed, 177k miles, spindles, hangers and shackles, 05 GMC wheels.
