Hi all,

sorry if this is the wrong forum but had no return from the 'tires' forum, and since i'll need th info before this friday, I thought it'd have more exposure here... so here's a copy of my other post. (if this is against forum rules, mods feel free to delete).

Hi all,

I will be moving from the stock 265s to 285/75/16 in a few weeks, but I'd like to only change 4 tires and keep the spare stock. I'd like to keep the spare for different reasons, one being $$$ (!!!) the other being that I'd like to keep my spare tire cover which I assume will not fit the 285s.

Do you guys think it could be a problem if for example, I had a flat tire and had to run to the shop with three 285s and one 265 for a few miles for a tire change?

thanks all for your help,

cheers,
JAM.

 

You can't run different tire sizes. They must all be 265 or 285. It's cheaper to get a new tire cover rather than screw up your tranny and 4wd.
Nice to see some schmuck has enough time on his hands to post such a classy "response". Hopefully the administrators can block this schmuck.

 

thanks for your reply. that's what I thought too, but was wondering since the spare would, if ever, be used to go from the site of tire puncture to the next tire shop... of course, another tire cover would be cheaper than a drivetrain!

Re:the schmuck... what can you do... WAY to much time on his/her hands. Has posted all over the forum in less than an hour. He or she would be better going out to the gym, work, clean the house, save $ to buy a Hummer, ****, whatever...

 

Schmuck banned.

Yep. You have to run all 4 tires the same size, even a very short distances.

 

Thanks Doc! (for both the answer & the schmuck!)

 

Doc
How about those little "Donut" spares. Aren't they smaller? Good for about 50 miles.

yes, I was wondering too...

 

never seen one on a 4WD truck. My H1s have runflats in them though which are a different diameter than the tire though.

 

Who was the Schmuck lol?? I got a PM from someone saying something really racist or something.. must have been him?

 

Due to the 4wd system of the H3 - full time 4wd - you cannot run tires of ANY size difference. No donut tires or even a spare that is one size smaller/larger whatever.

Doc or any of the other guys on here with a lot more technical knowledge than I can explain better. It'll screw up the full time 4wd system.

Point is you cannot run - even for a short distance - a tire that is a different size than the others.

As far as the schmuck he/she/it is gone and doesn't deserve any more "attention".
