Aftermarket wheels+flat+spare=???

[RockyMtnGT]

Just wondering how any of you running aftermarket (alternate size) wheels are planning on dealing with a flat tire should it occur?

 

I have Kuhmo ASX's mounted (225/40) on 18" Rota's, which (when new) are fractionally smaller in total circumference than the stock wheels/tires.

 

So given the fact that we are not supposed to run tires that are different sizes at the same time (due to potential differential/drivetrain damage)

 

How would we go about dealing with a flat, should it ever occur?

 

The last time I got a flat, I was in the city, so I just had the car flat bedded to Discout Tire, but what if I'm up not in the city? (150 miles up in the mountains, etc...)

 

I have a can of fix-o-flat or whatever, but I hate to use that sh!t. Do I need to buy an extra 18" rim and tire to keep as a spare? Even then, if the 18" full size is new and my other tires are worn, then what???

 

Just wondering if you all have any good suggestions because I'm confused!

I have a full size brand new spare...but as you've seen in my thread...I should not put it on the rear.

 

Worse come to worst - and a rear blows - you will have to change 2 tires: the full - new - to the front (open diff) and then take a worn front and put it on the rear (ltd slip). And crawl...

or rotate the spare into use during every oil change? that is assuming of course that ur 18" spare is the same wheel as the rest of ur wheels.

i still have my donut in the trunk but I also have 2 cans of fix-a-flat for emergencies

1/2 worn stock tires are the same OD as 225/40 18.

I think having a donut on the front is acceptable given the open diff.

Get a full size spare, or keep one of the 17's for a full size spare. Its just untll you get it fixed.

How big of a wheel and tire can fit in the spare tire wheel well. I am assuming it can be modified a little.

Thanks for the responses guys!

 

I made it back from the road trip pretty much unscathed- no flats...but I did hit a frikin HUGE pot hole though and was SURE it was going to cause a blow out. It seems to be ok though. I swear the impact was big enought that I thought the airbags might go off I'm almost sure it kicked off a few new rattles in my dash:mad: I haven't hit a hole like that since I lived around NYC...

 

I still need to crawl under the car and see the inside edge of my rim is bent.

The Rota's are damn tough though. I have hit some biggies before and haven't had any rim bend on me yet!

Hey guys same problem here.. Just put 18" konigs with 225/40 and wondering about a spare the tire store told me you could use any size spare as long ad the tire remained a 225?? Is this correct? Or can I just use a stock 17 i believe it's only a 205? So if I did have a flat I would have to put the spare up front NoT in the back?? Thanx

I know the front diff is open and the rear is LSD, but the owner's manual in my car says spare tire should go on the rear only.
