I have always used the stock size tires on my bikes. On the Enfield I even intend to use the exact same tires that came on it, more for looks than anything else. I do not ride it aggressively. I prefer to just enjoy the feel and sound of the bike.

I am by no means a safetycrat, but using the wrong tires on a bike can sometimes even be dangerous, especially if you are an aggressive rider. Modern sticky tires might not be a good match for the Enfield's ancient and flimsy frame and suspension.

Hi Suitcase, The Stock Avons felt snaky & rather frightening on my 2010 G5 deluxe. I replaced them with the same size Dunlop K70's Front 19 x 3.25, Rear 19x3.50.
They ARE the correct looking vintage for the bike. The K70 tires & stiffer rear shocks make mine handle like a racer, & make me feel a lot more confident & secure. The Dunlops are much cheaper than the Avons as well.
  Those rear AVON SM MKII tires make better sidecar rig tires than solo.

I noticed an immediate difference on my 1st ride over the stock Avons. In this area there is a lot of road crack repair done with the aerosol tar crack filler or "tar snakes" "road snakes" whatever one may refer to them as. On the stock tires I noted considerable wobble when crossing them. I don't now.

I like to refer to the stock Avon tires as track-masters.  They track every groove in the highway.  But, being a cheapskate, I still have them on and just try to avoid highways with rain grooves. I just try not to lean over too far....

Sorry to bother everyone; but should a 3.25 x19 tire fit on the front of a 2014 C5 Classic?
They list the K70 in a 19 at NFG.
I just put new shoes on my gal and she's wearing IRC GS-11's now.

I'm finding that the indented area of my front fender, between the fork legs is just lightly touching the tire. I need to figure out how to get just a tad more space in there.

So, where did you buy this tire?

Do you have any mileage info on it?  I'm only getting a few thousand miles on the rear K70's, and I'd like something reasonably safe that looks the part, but with a little more longevity...

Mattsz,
I got the tires from Central Maine PowerSports. They were about 60 something for the front and 70 something for the rear... or vice versa. I had mentioned these tires a while back and one of our forum buds... Craig, I think, mentioned that they have used them in the past and were happy with them. I'll let you know about mileage... in a while but if you google them there are a number of bike shop pages like Bike Bandit with numerous happy reviews. I didn't feel like spending a bunch right now and they have an old school look to the thread. They feel good.
Now I just need to figure out the best PSI to run them at for me and my C5. I'm think 20 front and 30 back? Not sure yet.

20psi is low inflation in front, I'd try 28. Rear is probably ok at 30psi, but I usually go 32 on mine.

I've gone with Mitas tyres after having a couple of nasty front end slides with Avon skidmasters. They still have the traditional look but are far better on grip and stability. Not sure if you can source them in the states though.
I run the front at 28psi and the rear at 32-35psi depending on the load, seems a lot better than the oem recommended pressures.

ok... just did the math run this morning. I set the air to 25psi in the front and 30psi in the back. Went for a good run to warm up the tires and checked the air while they were warm. Rear was at 33.5psi warm and front was at 26.5psi. This tells me I should probably run about 24-24.5 in the front and 29.5 in the back if I am doing my math correctly.

I run 25lbs in the front and 30lbs in the rear - I weigh 180lbs

So far so good.

Bike is a 2014 C5 and I'm running Dunlop K70s front 3.5X19 and 4.00X18
