My 1967 camper has stock rims but 15. Maybe the rims where replaced from previous owner. What size tire be good for 15’s? I imagine 205 / 75 / 15 it be too big
I think the 65-67 had a 4.375r&p with the big nut. It was the small nut busses that had the 4.125, with exception of “little big nut” and 64 with the 4.125 and big nuts. I’m having issues pushing 60 in my 64(4.125 and 1.26 boxes)with a 1500 running 205/70r14 tires. I wonder if you think a 1500 could push a 3.44 with a .89 4th? I like the idea of having a higher speed in the lower gears. I think vw realized that 4.125 R&P with the big nut boxes was a little too tall stock. It is a long slow pull with the 1.5L from 43-60mph......
Mike thanks for so excellent video where I can purchase 3.44 ring and pinion for my Brazilian split window 1974 I’m running reduction gear box what’s your input what should I look first in this bus
Hey Mike what about for a 71 baywindow. I'm running a 175/65/14 rear tire, I did lower the bus with 4 inch narrow front beam, with 2.5 inch drop spindles, and the rear im running 3.5 inch horse shoes. What size can I go with to lower my rpms on the highway?
honestly that is the bare minimum IMO. You would really like the 3.44s Some day make the upgrade. Even at 65 you can really have a conversation with someone else in the car. not too loud but still plenty of air through the engine. Runs super cool. gets it in that air RPM sweet spot. you could have Benco do a bench on the Box only put the boxes on yourself and have some passing speed. I was passing a boat and trailer on my way to Havasu for BBB and had to hit 85 for a second. Did it no problem.
@@HERBYWALLACE3 can you believe that the Bentley says cruising speed is 65 with 185 sr 14 and passing speed is 70. that was seriously screaming. No wonder there were so many blown engines and cut fender wells on these busses.
went to your trans guy's web site and he's not listing any trans with 3.44 r&p , that r&p is hard to find, i'm looking at a web site listing it at $400 with very limited quantity, i'm tempted to go that route rather than purchase a .82 4th.
Hey Mike. Great Video. I have a 2007cc and Freeway flyer in my 68 bus. I have the Hankook Vantra Commerical tires on my bus. 63 mph on the freeway feels like the engine is winding at about max comfort sound. Would a different size tire give me a few more MPH? Where did you get your double freeway from? Thanks Mike.
Rambus needs one of those Rancho Freeway Flyer trans. + I would like a center mount 2bbl carb. I have a W 100 Engle and its a DP with D-port heads , Quiet muffler that the J tubes are welded to the header pipes. I have 205 - 75 - 14 s I have no idea if it runs 70 mph anymore .
About using a jack to push the axles down on a lowered Bus. It can depend on a lot of things. How low the Bus is, wheel size and offset, tire size, and the year of the Bus. On 63’s with the flat wheel arches have a lot less clearance then a 63 and up. I’ve had a few mildly lowered 64 and up Buses with aftermarket wheels and 205 width tires, and didn’t need to push the axle Dow to change tires.
Wow I have not heard that. Most of the guys I know need to jack the arm down to get the tire off. or have super small tires that defeats the gear ratio problem.
Hey Mike. Got a question for you. If we have the 1500cc industrial engine in our bus, supposedly has about 60 hp, would we be able to put a 215/75r15 on to gain speed? Gonna need power for our trip to California.
I have a 66 camper and was wondering if I do change sizes of the tires, do you have to do anything with the speedometer to make sure that it is reading the proper mph?
you would need to do that. fortunately there are people with 3D printers who can help you with this problem. example: www.odometergears.com/products/Volkswagen/Mechanical+Speedometer/19
busses are light enough for passenger car tires. On my bucket truck I am using more sidewall Trailer tires because truck ones are not readily available in that size
You are correct , but at top speed in3rd is 45mph but to geto 55 in 3rd is ok to pass but prolonged winds myorv up the 4.125 ring pion set was only found unused up to 63&HALF.VWOF BRAZILRAN 4 125RP W ITH CLOSE 3RD &4TH,FROM 1964 ON THE RING AND PUON WAS 4.375 REDUCTION WAS 1.26
So the tire he has on is basically 26 in tall so if you want a low profile you would need to go to a 17 in with 215/55/17 which is 26-26.3 " tall on the rear. That's what I get if you want after market wheels.
Hey mike Im running a big nut trans with gear boxes. Its a 3.88 with .77 4th. So it comes out to 3.76. Paired with a 1915cc. I recently went to a show and some dude was saying im gonna blow up my motor. The motors not the healthiest but it still feels strong. Im also running 205/85 15 in the rear. What do you think?
I dont think I have ever heard of a 77 4th. I have heard of a .79 but I am not totally sure they make that for a bug or bus trans. Those were in Rabbits. but I am not sure if they can be used in a rear wheel drive car.
no that would not be a problem with too low fan speed IMO lower gears than bug 3.88 even with those numbers. final drive 3.45 but your tires are taller so your about the same as a 3.88
@@Mikefngarage thanks mike! Some peace of mind lol. Dude was saying if your running the gear boxes to get a factory size motor to be the perfect combo. Worst comes to worst i was thinking of a 1641 or 1776 with efi. Low budget out in orange seems to be the specialist for efi builds
My '58 bus has the stock split case tranny, and even with 205/75-15s and a built 1776, I'm pretty much maxed out at 55. Anything i can do to mod the split case to get a few more mph outta the old gal?
I would usually change to a big nut later model trans. The split case usually had 4.375 gears with the .82 4th. small nut 1.39 to 1. Stock Big nut had 4.12 .82 and 1.26 to 1. I change them up to 3.44 .89 4th and 1.26 big nut. then you can go as fast as you want. Even if you find a stock small nut from a 61 and later that would be better because they had the 4.12 my truck goes 60 max. with later trans.
I need tires bad for my 70 VW bus it has 205 70 14 is there a tire that's just a tad bit taller I can run to drop the RPMs 0n the freeway ever so slightly maybe a 215 70 14? Or staggered 205 70 14 front? I read so much crap I'm just really confused now😂

wow you are good at math! :) this is some seriously knowledge in this video

What about late bay setups? IRS and cv axles seem to be better overall, can those be put into a older bus?
with lots of modification yes. Some guys put bay window total rear suspension on the early ones. I have never done that though.

I run the big tires in the rear and near stock tires in the front. so the speedo is correct.
you would need to do that. fortunately there are people with 3D printers who can help you with this problem. example: www.odometergears.com/products/Volkswagen/Mechanical+Speedometer/19
Lots of good info. I heard that you are supposed to run “lt” light truck tires on vans and not passenger car tires.

15 on early ones pre 64 and mid 64 and up 14 inch.
