#118 of 788 bolt left inside new car tire at factory
Oct 18, 2008 (9:53 am)
One of my many sisters bought a new 2006 Highlander, 2wd. They have always complained of some noise in the back that nobody could ever find. This thing only has about 30k on it, and she is the original owner. She had a left rear blowout one day last week, with a very strange hole in the tire, that resembled a bullet blast from inside the tire. I was moving the tire from the back hatch to the garage, when I felt something big and heavy rolling around inside the tire. After breaking one side of the tire, I was able to retrieve what looked like some type of self threading body bolt. It was a sort of green, about 5 inches long, 1/2" diameter, with a large washer head on it. The head must have wedged it self against the inside of the steel wheel, and when she simultaneously hit a pothole, it blew a hole thru the tire like a grenade. The bolt was quite scuffed up, and by the looks of the thing, it has every characteristic of any object that would have been rolling around the inside of the tire for 30,000 miles. She has called Toyota, and they have never called her back, not that anyone on the phone would believe her, and she is reluctant to call an attorney. I think they at least owe her a set of tires. Anyway, my question to you is; "have you ever heard of this, and how often does it happen, and I wonder if it was some sort of factory sabotage, or resentment on the part of some employee?

If everything works good, and then you have trouble within 10,000 miles, then you need to go back to Toyota original pads. It sounds like you have a heat and dust build-up problem due to non-compatible materials in the pad composition. I know this sounds a little far fetched, but I can tell you this from personal experience. Having owned quite a few Toyotas, and 3 of my current 6, have between 200 to 350k, and I do have one with a little over 500k, and that one has only had the calipers rebuilt once, and the master cylinder and lines are original. I learned a few lessons about 10 years ago with aftermarket pads, and since I went back to oem pads, things have been problem free.

The only thing that should be inside a tire is a valve stem base and a tire sensor monitor. The bolt--from your description--seems too large to be part of the tire sensor monitor unit.

I have a 2005 Highlander 2WD with the 225/70 -16, and use snow tire in the winter.
I needed fair weather tires, for Hwy use only with fuel mileage, comfort, and noise as the priority. I ended up with the Kumo Solus KR21.
I like the price (under $120 installed for each tire), the warranty (80,000 miles with road hazard), and the noise levels. Oh and they are way better that the O.E. tires.

I just bought new tires for my 2006 Highlander and the tire store suggested putting 235 tires instead of the 225. Does this make a difference? My Toyo seems to drive very different with no play whatsoever in steering.

I am not sure what affect this may have on your Toyo. Larger tires may change speedometer reading to be off just a little. I live in Montana where we drive in a lot of snow and ice in the winter and I have noticed ice and snow build up between the rear tires and springs. Larger tires would mean less clearance but probably not be a big deal. I think larger tires cause speedometers to read slower mph. I noticed a 5 mph difference on a truck I put larger tires on. I was going 55 on speedometer but 60 actual speed. Yours might read 2 to 3 mph off. Someone out there might have exact difference. Not an expert on this for sure!! If it drives and handles well, you made a good decision to go with larger tires. Only time and Toyota will tell you if larger tires will affect drive train, transmission, AWD, etc.

the difference in this case is very, very small. the 235 tires will be a bit wider (10mm, to be precise). The issue to be concerned about is that as the width changes, the height of the tire (sidewall) changes too, even tho the # after the 235/ will be the same.
That number (the xx in 235/xx) is really a RATIO, not an exact dimension. So as the width gets wider, the sideway get taller if the same # or ratio is used. Therefore a 235/40 is a bit wider AND taller than a 225/40 even tho they are both /40. ( i use /40 as an example; I don't know what the # is on your highlander)
It's the change in sidewall height that can cause the issues with speedometer accuracy.
However, in this case the difference is so small that you really won't notice any change at all. A change of up or down 10mm is almost always of no concern.
If you want to play around a bit, tires.com has a calculator to see what happens as you change tire sizes. It even shows you how much your speedometer will be off.

years ago I moved my camry from 195 all the way to 225 (a 30mm increase!), and in doing so also changed the sidewall # so as to keep the sidewall height the same and avoid any speedometer issues.
The advantages of wider tires are better traction in all conditions (simply more rubber on the road). The downside is that more rubber on the road can hurt gas mileage (higher rolling resistance). The other issues about wear and tear and torque and all that are largely inconsequential considering all the real factors that apply. I have had the +30mm tires on my camry for over 200,000 miles (not the same set mind you!) with no problems whatsoever.

Well, if you live in snow country (like Montana), you may find that a skinnier tire digs through the snow down to the pavement better. More rubber from a wider tire can cause you to float over the snow and lose traction.

Thanks Kenlw !! I knew there was someone out there that is far more knowledgeable about this subject than me. That is what is great about this forum. I did not clarify, and should have, that the tire size change on my truck was significant. Completely different rims and tires. I apologize for that boo boo.
Appreciate Kenlw responding and pointing out that there is not much difference in these tires affect on the mph and vehicle in general. I will be more careful in future posts.

Yes, steve, the larger footprint of a wider tire DOES reduce the pressure (caused by the weight of the vehicle) since it is spread over a larger area (footprint). The change in this case would be about 4 sq in of contact area assuming a 12" long footprint.
But the tread pattern will negate this in the case of liquids like water. Which for us here is a bit more common than snow...... and beach sand is a solid that we would really not dig down thru!
