Tire size and gearing

[MAS Tequila]

My 2000 Mounty has the V8 with the 3.73 gears.

I've lifted it and am looking to put tires on soon, maybe this weekend.

I have a set of 04-14 5 spoke Mustang wheels 18x8.

I'm trying to decide between the 265/65/18 31.5" tall, and the 265/70/18 which is 32.5" tall.

If anyone has run a similar size tire, will it make much of a difference, or should I stay with the 265/65?

I really don't want to re-gear.

Thanks

Your effective ratio will be pretty low. Something like 3.23 or something with the larger tires.

Fast off the line- you won't be.

What size are you running now?
What size came stock on it?

So that's 29". You'll definitely notice a difference, even just going to the 31.5s, but it should not be a problem running either size, IMO.
My Ranger came new with 3.73 and 30.5 tires, and it was not piggish at all. You having a v8 will more than compensate if you decide to go with the 32.5s.

If you google for tire/gear calculators, you can see this all laid out in a chart.
