No you do not. Bigger tires and wheels have nothing to do with it stopping.
Yes you can put bigger tires on your existing wheels up to a point. Talk to your local tire dealer and they can advise you on the biggest tires you can use.
You recalibrate it because bigger tires mean different speeds... for example, lets say your car had 14 inch tires... and your speedometer is saying that you are going 50, if you add 20 inch tires which is 6 inches bigger, you might be going around 60-70. No need to get a speeding ticket. Bigger tires cover more road then smaller tires, for example for ever 1 turn from a 20 inch tire is like 1 and ahalf turns from a 14 inch... Hope Ive helped you understand why :)
yes u can but u need to buy some parts for it
You may need a new steering shock, rotate tires or need new tires. A new steering dampner shock, or front break rotars.
A tire alignment is not necessary when changing tire sizes. You can tell by the wear on your previous tires if you need an alignment. If you have uneven wear, get an alignment.
You need the tires that are most appropriate for your car.
Generally means your break pads/shoes are worn and need replacing. If you let it go too long without fixing it will grind down your rotors as well in which case they will also need replacing or resurfacing.
The difference between tire sizes is 1.29in. So if on your 185/65-14 tires you have an extra inch and a half of slack adjustment they will more than likely work with the bigger 70 profile tires. Remember that if your tires are quite worn when you put the chains on you will need more than 1.29'' of slack because the new tires will have more meat on them and a bigger diameter.
No, you need the tires with the air in them to tow it.
Kelly Tires offers a wide variety of tires, whether you need "all terrain" tires for all road types, tires for rugged terrain. They have commercial truck tires or "LT" tires, tires for light trucks. They tell you how to locate on your vehicle the correct tire size you need.
bigger vehicles usually have bigger engines which take more fuel to crank the motors and turn the tires which is why you are gettin worse gas mileage
You don't need to rotate MY tires but, you need to when your car goes left or right when the wheel is straight.
