Rear: 265/35R18 Diameter - 25.3
Spare tire: 105/95R17 Diameter - 24.9

So if I have a flat tire on a rear tire is it ok to use the spare or is the diameter difference going to screw with my tiptronic transmission ?....I seen someone say something about taking off the rear tire then taking off a front tire and putting it on the rear then put the spare on the front.

And I run NGK plugs in everything I own and I want to convert my 99 base 2.5L over to NGK's....So can someone confirm that it would be a NGK BKR6EK (2288) ?
For how long will you be driving on the spare, regardless of where it is installed? You might consider driving it to the nearest tire repair shop, and as quickly as possible. You might also consider examining your tires at least once a week. An ounce of prevention is worth a pound of cure.

Is everything you own a domestic? Maybe consider just running OEM plugs. Our cars aren't Hondas.

What oil do you recommend? Have you had your IMS replaced? What brand tires are you running?
