Thread: Please read: Posts on 19" rims

I guess the point I'm making is the fact that the tyres took a really hard hit and didn't smash against the rims...thus causing a puncture. After the gravel work that I've done, still no tears or scollops either. Has anybody on this site reported destroying a standard 19" under non-crazy driving circumstances?

Also,tyres can be damaged,some people call it "bruising",and may not show any sign of a problem,even if taken off the rim for a thorough inspection..A problem may occur later in the tyres life.
If it was my vehicle,i would push to have the front tyres replaced as well.

It is possible to shred even the toughest tyres, or by pure luck take say 21" roadies on a rough road and not damage them. Also, those that do go offroad will be swapping rubber. I've driven 19 roads offroad and had no issues, but a weekend doesn't prove much in the way of tyre longevtiy.

What I can definitely say is that any road tread/passenger construction tyre, and particuarly the higher-speed rated low profiles are not suitable for ongoing dirt road or offroad work.

The hit on the tyre wouldn't damage it anywhere near as much as a rip or tear. Offroad tyres have deep tread blocks (say 15-20mm) so if you rolled over a 14mm tall tack it wouldn't touch the carcass. Do the same with a road tyre and that same tack would go right through the blocks and penetrate the carcass. Also, the offroad tyre's carcass will be thicker and stronger.

Note that there is also a difference between the passenger/road tyres fitted to the likes of Japanese utes and the passenger/road tyres fitted to the 3.0 D4. You wouldn't want to run at high speed on the former for too long!

If you asked any experienced offroader what the four things to change on a stock vehicle are to make it into a tourer I can guarantee that most of them would put tyres high on their lists.

All good points Robert, guess I'm thinking that as time goes by and there are more 19" rims on the road (as I hear the Japs are planning on a lot of 19" releases) that the manufacturers will cater for the need and make better, tougher tyres. Obviously the points you made regarding tread and sidewall thickness/toughness wil be an issue until this happens....better construction may...may....help.

Also I still don't think I'd be tackling anything too taxing in the tyres I currently have but when I fist started reading about them I expected to get a punture at the first rock I hit.....which certainly hasn't been the case at all.

Tread size and ballooning....well...who knows...LOL!!!

Thanks.

Good point Paul, I talked to the smash repair today and we discussed getting the tyres checked out too.....but like the 'undercarriage' of the car, it's hard to push the case when there are no obvious signs of damage.

The smash repair is going to send the car off to a suspension and steering specialist to get checked out, as I've really pushed that point....as now being paranoid, am feeling slight movement and looseness in the steering, etc....

Singularly disappointed in LR though. If I was LR, since the car is under warranty and the owner approached me....I'd jump at the chance to get EVERYTHING checked out...so that it didn't bite me in warranty claims later. But no....completely uninterested! Unbelievable!

After hosing the built-up mud from my rear 19" rims yesterday, I found 1 rim has been seriously gouged by a rock yet the Pirelli ATR tyre is unmarked. The vehicle has not been "off road" although I do have 2 kms of sometimes mud-puddle driveway and 4km of gravel road before the bitumen. I'm still waiting for the 2.7 brake parts to arrive.

So far, I have had 3 of my 19" rims re-done from scratches. One occasion was when I was bogged up against an embankment and the rims were spinning against it.
This is why I brought a set of second hand rims with MTR's.
