2WD: on the front tires 4WD: on the front and rear tires but Honda Pilot 4WD is not a full 4WD therefore no need to put chains in rear tires unless you're manual engage 4WD.
4WD is better in my opinion. I'f you don't know the difference it is that 4WD is were you have the option of engaging the 4WD feature whenever. AWD is common among more luxuriated "off road vehicles" and when the tires lose traction a computer within the vehicle will activate the AWD feature to re-gain traction.
Tie the tyres up with a chain to another vehicle, then accelerate and pull it off.
4wd or 2wd? If 4wd yes but if 2wd no!
Driving in 4WD mode on dry roads can cause that. Also, mismatched tires can do that too.
I believe if you open the drivers door , on the end of the door is an information sticker that will show the original size tires that were on the vehicle from the factory
If they are regular tires and the tractor is 2wd they are 11.2-24 and 4wd they are 9.5-24 If they are turf tires and the tractor is 2 or 4wd they are 41x14.00-20
A used tire is a tire that has been used on a vehicle before. Retread tires are different in that they have been used before, but then they went through a process that extends their life. Retread tires are kind of like "refurbished" tires.
Best used tires keeps several hundred tires on stock at all times. Contacting them will be the best way to see if they have what you need for your specific vehicle on hand.
Nitrogen , check out this site, http://www.getnitrogen.org/ Typically, plain air. Nitrogen is used in high-performance racing tires and in large aircraft tires.

No, but make sure all 4 tires are the exact same size. No exceptions to this on a 4wd vehicle. Also if the tires are worn badly I would recommend you replace both tires on the same axle at once. The wear difference in a new tire and worn tire on the same axle can cause the vehicle to drift or pull to one side. If your rotate your tires as you should all 4 tires will wear evenly. That way you replace all 4 at the same time which is always the best.
