Yes, I have thought about doing that.

But with the left knee replaced about 3 momths ago and the right knee to be replaced on 2 June - for once I let my top head do the thinking and decided against it.

Btw - thanks to all of you for your answers.

Hmmm yeah... that's a good decision


I have my 265/70-16 under mine with no problems found. As far as using different sizes on same axles that is something that I would avoid. I know that in the past Jeep had a recall on their spare tires that was approximately 5mm taller. Even with minimal use for emergency purposes they destroyed the viscous coupler in their all-wheel drive platforms. There was a lot of warranty money paid out due to this problem.
Tell that to all those who drive with 4 mismatched tires. Although it's kind of interesting, because a lot of car manufacturers are now using the space saver spare, including in AWD cars and even some small crossovers.

Saxis,

If you want a full sized spare for offroading but don't mind a smaller spare for highways, you can get the spare and then just carry it in the trunk (a la Jeep). Or you can carry it in the trunk all the time, but it'll take a lot of space. Old Blazers were like that.


DZP,

Are you serious? the space savers always looked way smaller to me, but the last time I used one was back in 97 or so. And they are rated for only 50MPH, at least ours was (my dad wasn't too happy about driving the remaining 2 hours of the trip doing 50MPH, which of course got extended to 2.5 or so).


I wonder what GM did with the Acadia/Traverse/Outlook/Enclave in terms of spare tires. A friend said that 2010 Escalades come with a fix a flat instead of a spare, which is a really stupid idea. hopefully that got ditched in favour of a real tire.

I'd see that as very hard unless you have decent spacers, the upper ball joint puts enormous limits on everything.

I'm definitely not going into the extremes and staying around 265/65/17 or so, probably the biggest size w/o spacers or the next one up (and the spacers). And either Dueler A/T Revos or Silent Armors. I'm sticking with my current tires until the first one gets damaged beyond repair, then I'll replace all 4. I might just keep the original spare for general use. Maybe at some point get an extra wheel and full size tire just for off road trips (having 2 spares would. be awesome).

And I haven't done any real mods. The first one will be the tires and possibly spacers. Then I'll consider a small brushguard. I've focused mostly on interior accesories (CB, 2M, nav GPS. In a few months I'm chaging the power distribution for my radios and possibly getting a 12V deep cycle battery for powering my radios w/o the car battery).
