Titan 18" on 77 620 Tire size ?

[wildmaninid]

Been a few years since I have been on the forum here...once I finished my 521 and sold it a year later I haven't done much Datsun-ing, but I picked up a 77 620 longbox and am starting another custom restoration. I do see a few of you guys running the Titan 18" wheel, I recently acquired a set, and am wondering what tire size to run...I was thinking 235-40-18, but am looking for some input from the community.

 

 

Thanks a ton for your time

225/40/18 is what I run and there perfect!

[wildmaninid]

this is a tire size calculator to keep the diameter the same for speedos, etc.

my question is with the 225 40 18 and the titans do you have to run spacers or anything on the 77 model, i have a 77 and titans too and i need to get them on there!! mine is dropped 3 inches in the rear and maybe 4 inches in the front, will they rub on the front??????

Your gonna need to roll the fenders but, other than that I don't think you'll have any problems since you have a 77 which have drum brakes all the way around.

You have to run 1/4" spacers or turn the hubs....or you can open up the center hole on the wheels. I just ran 1/4" spacers on my 77.

[Braden]

so 1/4 inch spacers all the way around? i would rather not roll my fenders :angry: maybe some longer studs!

[]2eDeYe]

You don't have to roll the fenders, although flattening the lip in the rear would be a good idea.

 

Flat lip, 225/40r18, 1/4" spacers..frame sitting on the axle...

mine will not be that low ever, just 3 inch blocks in the rear maybe 4 inch or 3 inch and some drop shackles

[]2eDeYe]

That pic is 3" blocks and a fully loaded bed ;)

anybody ever run 235 60 18 on 620 with a titan rim? i have a chance to buy a set for 80 bucks

[]2eDeYe]

Might fit if its stock height. Won't on a lowered truck.

im runnign 3 inch blocks and re indexed bars

Just want to ask if any one is running the stock drum brakes all around with this set up? I got a 521, just want to know how much stopping power is lost.

[]2eDeYe]

I'm running drums with mine at the moment, you won't notice any loss of braking. Upgrading to disc pretty soon though as the stock drums aren't the best brakes to begin with.

[alex843]

Yeah that is the plan too. I do a lot of highway driving, plus the 521 only has a single outlet on the master cylinder. That why I wanted to hear about some one else running stock brakes.

[wildmaninid]

Been running the 18" titan wheels since just after i started this thread, running 235/40/18 tires with 4 wheel drum brakes, and i haven't experienced and lack of stopping power. Fact it i just don't go fast enough to worry about it honestly. I love the wheel tire combo and would recommend it to anyone with a datto p/u.

 

Its a nice!

I have a set of these 18" Titan rims in my garage (I got KMC XD's for my Titan) and I keep wanting a 620 to put them on!

 

I do love how they look on 620's, it's a great match.

[wildmaninid]

OMG i forgot to show pics for every post, my bad LOL
