Never had a flat tire on my 2008 LC, but had my first yesterday on the (new to me) 2018. I was driving at a leisurely 20-25 MPH down the middle of the main street in Nashua, NH yesterday afternoon when KA-CHUNK-WHOOSH and my left rear tire went completely flat. I had three kids with me in the LC, only two of whom were/are mine, so very glad this happened at such a low speed. Limped around the corner and pulled over - tire was completely deflated. So, got out the tool kit and bottle jack and got to work in the blazing sun.
BLUF (bottom line up front): I gave it a good college try, but trying to spin that bottle jack up using the OEM tool kit hook contraption was just too painful, particularly with the sun beating down and gravel embedded in my knees, so I "called" AAA (via web browser) and literally about 10 minutes after that I was back on the road. Thank goodness for full size spares, and for calling for AAA roadside service right from a central, busy location.
When it was finally removed, the injured tire (relatively young Michelin Latitude HP Tour in stock 285/60 R18 size) had a huge radial tear, starting just above the bead and running almost to the edge of the tread. My guess is there was something like a chunk of angle iron on the street that was positioned perfectly to get flipped up by the front tire so as to just catch the sidewall of the rear tire as it passed the same spot. I’ll be checking the dash cam footage tomorrow to see if I can figure out what happened and if anything was visible on the street surface.
The longer story, with some lessons learned and some questions for the group follows below.
Spare Wheel/Tire
I know that the spare mechanism can rust / seize, but my spare wheel dropped down just fine. However, the lug seating faces on the spare wheel were full of grit and sand and accumulated grime, so I spent a few minutes cleaning them out with hand sanitizer and napkins (all I had). Lesson 1 learned: bring along some Scotch Brite, paper towels and some sort of liquid general purpose cleaner. Question: has anyone thought of a clever way to plug the lug faces on the spare to keep this from happening? 22-24mm round rubber plugs, perhaps?
OEM Bottle Jack - Ground Support
The place I initially had picked to stop was softer asphalt, and it started immediately absorbing the base of the jack rather than lifting the vehicle…so I had to unwind everything and pull partially back onto the road to try again. Lesson 2 learned: pick a good spot, but also bring along the 12” x 12” x 3/4” plywood board that I have for the beach for use as a jacking base. Light, small and won’t take up much space.
OEM Bottle Jack - Lifting Mechanism
The hook contraption from the tool kit was binding repeatedly on the jack’s rotating closed loop, throwing the jack off kilter several times, which was super frustrating. This has sent me searching for jack alternatives, or at least a way to mechanize the process with the OEM bottle jack to eliminate the manual handle / hook contraption. I’ve read that some may have figured out a way to use an impact driver to spin the OEM jack up and down. (FWIW, the included scissor jacks on my previous Mercedes GLS’s use an exposed hex head nut and a reversible ratchet handle system to raise and lower that jack. The beauty of that system is that you can substitute a battery operated impact driver with a socket to turn the nut and move the jack up and down much faster.) Question for those who have gone down this road: can you just chuck the last part of the OEM hook contraption into your driver, or is there a more elegant / robust solution?
Tools
I was already going to order the jack adapter from Land Cruiser Products, but hadn’t gotten around to it yet…I’m sure it would have helped keep things running much more smoothly. I ordered it this morning. The AAA guy had an aluminum race jack in his truck, which made quick work of lifting the LC. Wish I could justify carrying one around, but I think it would just take up too much space. He did have a sweet 24” ratcheting breaker bar, though, which I hadn’t seen in the wild before. Bought a cheap one off eBay today, along with a super-long (non-impact) 22mm deep socket, so will give that a try. Will also throw an older pair of Mechanix gloves in the back by the bottle jack. A foam knee board would probably be a nice touch as well, so I’ll keep an eye out for one of those (gardening center, maybe?). Anything else I should think about carrying?
Tires & Wheels
The existing spare tire (a non-matching Dunlop, but with almost-new tread) is gray and dirty and the rubber looks dry, but it seems to be working fine so far. My guess it that it’s probably the original tire that came on the LC when it shipped from Japan in 2017. The destroyed Michelin was unmounted today, and I took a cut at degreasing and cleaning that wheel and removing the existing wheel weights. The back side / mating face of the removed wheel was surprisingly dirty / gritty, and the barrel was fairly dirty and gritty as well. I will be stepping up my wheel cleaning regimen going forward. The replacement Michelin is on order from Tire Rack, but hasn’t shipped yet. None of the area tire shops had any 285/60R18 tires in stock, much less the specific Michelin I needed. There are a bunch of them listed on eBay, ranging from “new” to 5/32” tread depth, and ranging from 114V to 120V - I think the “new” tire(s) may be take-offs, so I may buy one to replace the Dunlop after this is all over.
These stock wheels are tough, but HEAVY. I will be stepping up my search for a set of the TRD Pro BBS forged wheels shortly as well.
Anyway, I thought I’d pass this experience along to the group, as it’s not something that (at least) some of us think about too much. I know I hadn’t given it much thought before yesterday - I just assumed everything would work fine/as advertised if and when the need arose. If anyone has any answers / advice on the questions I’ve posed above, I’d certainly appreciate the assist.
