If im running 265/70/17 and say i have a blow out and i have a 265/65/17 spare is that to big of a difference in size to screw anything up?

I thought may be ok as long as it is on the front and not in 4wd or is that even nessisary?

Thanks guys..

Its highly recommended that your spare is the size of your actual tires. Go get a POS 70 series tire even if its bald and have that as a spare.
 
A Honda Pilot or other awd vehicles are EXTREMELY sensitive to overall diameter. The T4R will tolerate the minor difference of a fully inflated 265/65/17 spare. I prefer to recommend all 5 tires being the same as Eskimochaos suggested. If you take road trips a full-sized spare provides a nice piece of mind.

Truth is the correct answer depends on who you are. Do you put the spare on to go to the first service station and drive a little slower getting there or do you get around to getting the tire fixed sometime in the next 10days or 1500miles, whichever happens first? If you're in the latter category I'd get a 265/70.

If your existing spare is almost new go to some used tire place and trade the guy for a more worn 265/70. That might be free or very close.

You're ok. It's not that much of difference. There was someone in here who went off-roading and had 2 flats and had to borrow someone else's spare with two different sizes.

This was discussed a long while ago. IIRC, the concensus was...

If you have a V6 4WD, you can put it in 2H and put the 265/65 spare up front. Alternatively, you can lower the tire pressure of the 265/70. I'm not sure how low of a pressure the 265/70 needs to be to match that of the 265/65 and avoiding damage to the 265/70 due to low pressure. It's a bigger issue for the V8 4WD because they're always in 4WD.
 
Lower the pressure? Is this because the lower pressure means more RPMs? So you'd have to lower the pressure of three 70 series tires to get them to have the same RPMs as the smaller 65 series? It would be tricky to do, but I guess intheory makes sense. I think it is easier overall to just get the correct sized spare tire. Rotaote it in with the other 4 and it probably doesn't cost more in the end.
 
Kind of along the same lines. Though its never been driven on, the spare is in atrocious shape. The truck is an 04, but I suspect the spare is older than that. I'm not sure what my next set of tires is going to be, as I just replaced my CTs 20k mi ago. I would like to put a CT on the spare again, but 200 bucks is a lot. I've also been scoping out some 'newer' used tires. Will there be an issue with mixing up the brand of my spare? What if I get a spare with a more aggressive tread, like 'revo' not 'BFG K/O' than my CT's?

My spare is not in my rotation plan.

Thanks guys

Not questioning the collective wisdom here, but why would the offsize spare go on the front? Seems like that would affect turning and handling more than in the back?

Absolutely no issue if the O.D. is close. If I found a good, 'not-ancient' brand name tire in the same size I'd do it. I think you are wise to swap out the 6year-old plus spare. Maybe wait a month or so and grab a Firestone Winterforce on sale. Often times they run in the $80-90 range out of season and as a spare....

If you have stuck with 265/65/17's look at 255/70/17's too. They go on sale super-cheap too. These guys seem to run some strong sales...

Because the 4th gen V6 4WD can be driven in 2WD/RWD. So the different size tire doesn't affect the diff. Similar to how vehicles with temporary spares, they recommend the spare to be used on the non-drive axle to minimize wear on the diff.
