305/65 R18 Ridge Grapplers on 100 Series

[blakt out]

Hey everyone. This is my first post here, but I consume a lot of info on here. In all of my trolling, I couldn't find where someone had put 305/65 R18s on a 100 Series. Maybe I just didn't look in the right spot, but all I could find was speculation. I installed a Tough Dog adjustable suspension lift, which gave it two or three inches, (Sorry. I didn't measure.) and then ordered the tires, choosing Nitto Ridge Grapplers. I love the look, and I drive a lot on the street.

So, here are some pictures. There is no rubbing whatsoever. I have not put spacers on, though I am considering it for the look. I hope this helps out someone who is wondering how they will fit! Glad to be a part here, fellas.

There's a whole thread dedicated to this tire size

305/65/18 BFG KO2 Pics

I just had some 305/65/18 KO2's installed on my 100. I have been running 295/70/18's......I never really loved these tires. They were a bit too tall (34.5") and a bit too narrow (11.25") for my needs. Recently I bought some Slee Spacers to widen the stance some, but I was still not happy...

Thanks man. For some reason, I had it in my head that that thread was about 305/60s. I'll delete this and move my pics over to that one.

Off hand it looks like you may not have enough droop in the front. Maybe you have aftermarket UCAs. How does the steering feel on rougher roads?

Well, I actually don't know what "droop" is. Is that the amount that the front is lower than the rear? I do have aftermarket torsion bars, and also did a diff drop on the front. Not sure what UCAs are either though.

On rough roads, it feels pretty much like it did before, other than maybe a bit more jarring. I have assumed that that was due to the stiffer sidewalls though.

Looking forward to your thoughts and educatin'.

Nice rig, dig the color.

305/65-18 is perhaps the perfect tire for the 100 series. I’ve run 1/2 dozen different sizes and that’s the one that worked the best.

Droop is the amount of down travel front wheels have from normal ride height. So measure from lip of fender to center of wheel as it sits. Then jack up frame of Cruiser until front wheels are off the ground and measure lip of fender to center of wheel, it should be at least 2 3/8 inches greater than first measurement.
It is a spec primarily for t-bar suspensions because of the range of adjustment. Toyota specs a minimum of ~60mm ~2 3/8 inch of droop (down travel). Less than that the wheels don't follow the road surface as well and steering control is impacted along with ride quality. But all of that is in a number of posts here along with UCAs and extended travel shocks to get more height in the front. If you have watched some of those videos from the Middle East of putting 100s up on two wheels it gives you an idea of how easy it is to roll one. So any reduction of steering control would add to that risk.
