Have a chance to pick up 275/65/18 take offs for my truck. Michelin XC's for $300. Any downside as far as the size ? Truck will be stock height.

Re: New Tire Possibility

Dont see any downside as long as you have rims to put them on

Re: New Tire Possibility

U didnít list the size u have now but the stock size is just over 28 inches and the size u are going with is 32 in. Your speedometer will b off 8 mph at 55. If u donít have an aftermarket Speedo that u can recalibrate , you will have to change transmission gear or try and keep up with the difference when u drive. Also, u didnít list what transmission or rear gear u have so b prepared to lose some take off power as this height differences will make Lower rpms at normal speed.

Re: New Tire Possibility

Truck is in the 3rd year of my "project". Rear end is stock and I am sticking with the Saginaw with a slightly built 5.7 (325 HP ) I am putting in a new digital dash. Found a good sale on 18s at Jegs. They are 9.5 wide so should I go 9.5 all around or stagger with 8" on the front??

Re: New Tire Possibility

To help u figure this out quicker, cut a block of wood the difference n height from what u have to what u want. If u have a stock size on there now, then roughly 2x2. Use this on top to tell u how much taller u will b and when u turn the wheel lock to lock, use it on the top and sides to show u the space left over. Being as your truck isn’t lowered, u will have more of a gap then someone who has dropped 3/5 respectively. If u have the room all the way around, then no problem. But....if u are close or are touching, then using an 8 inch rim all the way around, might b the way to go. Thus why u use the block.this is just a simple and quick way to visualize what u will b stepping n 2. The digital gauge will compensate for the tranny gear and tire height difference.just remember if u pull something heavy and the rear gear is 3:73 now it will b more like 3:23 with those tires.
