Has anyone raised the tire size on the rear instead of putting in a lift kit on their TG. 255/75R15 would fit. Yes it will also change speedometer. I have 2013 TG

You would have to increase the sidewall by 1 1/2" over stock sidewall to accomplish what the Lift Kit does. Plus the lift kit practically eliminates the rake look of the truck relative to the rear tires.

 

They would have to be very tall, very skinny tires! Think that would look kind of crummy. Don't think you would have the clearance front and rear. Either leave it stock or put the lift kit on.

 

The speedo is the least of your worries !! You would change the final drive ratio by at least one gear. Like taking off in second gear. You wouldn't be a happy camper for sure !!

 

This is what I did, I replaced rear tires on TG with 225/75R15. Raised TG 1.4 inches. Handling greatly improved. She does need to have new cams for sure now. She will get S&S 557 cams 2 July and will dyno 9 July with TTS tuner. The ride is a lot easier on the butt and back. Running 21 # pressure in tire. Just finished 250 miles on her. Going to is how 24# feels in her and add some more dyna beads for balancing. Only had 6oz so put 3 in each tire. Will add 1oz more to each and 2oz to front. with new tire gear ratio should be closet to the ultra. 10% increase over all gears. done at the tires and speedometer is 10% under actual now.

Pretty sure your tuner can correct the speedometer with the TTS when he tunes it.

 

Have them change out your cam bearings while in there torrington's.

 

Good luck with your tire change. You have now changed your final drive ratio to worse than the '09 & '10 MYs.














Speedometer Difference (Speedo Reading / Actual Speed) 20 mph / 22.19 mph ,25 mph / 27.74 mph 30 mph / 33.,29 mph ,35 mph / 38.84 mph ,40 mph / 44.39 mph ,45 mph / 49.93 mph ,50 mph / 55.48 mph ,55 mph / 61.03 mph , 60 mph / 66.58 mph , 65 mph / 72.13 mph

 

Maybe a dumb question but i am getting ready to trike my 09 ultra. I am planning on a 18" preformance machine front wheel with a 130/70/18 Dunlop Elite 3 Touring Tire on it. On the rear I will be using a 17 x 5 preformance machine wheels. The trike body manufacture usually put 225/60r15 on but I am looking at using Dunlop Direzza DZ 101 tires that are sized 245/45r17.. Not to worried about the speedo due to having Medallion Gauges that I can setup/ recalculate using my GPS. Question is will I encounter some of the same that you all are talking about as far as Power?

 

As compared with what you say the trike kit mfg puts on, No, the overall dimenitions are very close to each other.
But, you will probably feel/be underpowered with the 32 tooth primary pulley. That is why most of us changed to the 30 tooth pulley which is standard on the '11 and up TriGlides.
