Front or Rear?

I'm running 24 psi in my RT.
I used to run 28psi; when I still had the Kenda...
I could probably drop down to 22 psi... but I start getting nervous (For no apparent reason! )

Bob,

Just to be clear, you are talking about the rear tire with those numbers, is that correct? But, the OP asked about recommended pressure for car tires on the front. I believe in Mike's reply to you, he was also thinking "rear tire". I recall when Derrick installed my new Yokohama on the rear, he recommended 20 lbs. But like you, i'm running it at 24 - also for no apparent reason except my "comfort level". Considering the load I put on that back tire (with me plus the "stuff" I carry) it seems to be performing and wareing well at that pressure.

In the front, I run with 17 in my OEM Kendas, but if I had aftermarket tires with better sidewalls, I'd probably experiment with lower numbers on the front tires.

Mr. Bluenight, if your qualifications put you on a level not to be questioned then perhaps they should be mandatory reading for all new members. Not trying to make an issue of it but we all put our pants the same way so we are all on equal footing and are entitled to our opinion.:thumbup:

My posts on this thread ( prior to yours ) had absolutely nothing to do with or about you ....... However for some reason you felt compelled to make a SNIDE remark ( which is different from an OPINION )...... So enlighten me as to why you felt that it was necessary, because I'm completely baffled :dontknow: ????.......Mike :thumbup:

In post #5 of this thread you state that your qualifications give you the title of expert in this case. I merely pointed out that the bar to be an expert on the internet is a moving target. That wasn't snide just fact. You chose to take offense and label me a dumbass without reguard for my qualifications or experience. I don't take offense but consider the source. I'm here like most to gather and share information about a machine that we own or are considering and the opinions are like belly buttons, we all have one

help with Tire pressure

to the OP before this thread gets pulled, I run 20 in the front and 18 in the rear, conti's and kumo respectively. Great wet road traction since reduced the pressure on rear from 26 to 18. Thanks to Peter from down under's logic I am comfortable doing this.

Think about how much weight is in the tire on your RT compared to a car of 3000#'s.

My comments, as always, are worth exactly what you paid for them

:shocked: How about a round: "On the House"?



And Rob: you were 100% correct... :shocked:
I missed the reference to it being about front tires. pps:

This all falls on me: SORRY! nojoke

Do over

For anyone running aftermarket front tires, specifically Kuhmo, what tire pressures are you using? Just trying to get best mileage, traction and comfort on my 2015 RTL

I'm going to be replacing my stock fronts next season. I wish yokohama made one that would fit ray:. Can we start from the beginning of this thread again cuz I'm wondering what the consensus is on this.

Tire pressure on MY ST 2013 SM5...

For anyone running aftermarket front tires, specifically Kuhmo, what tire pressures are you using? Just trying to get best mileage, traction and comfort on my 2015 RTL

After experimenting on wet and dry all summer, with Kumho KH16 (175/55R15)in the front, and Kumho AST (225/50R15)I. settled down to 16.5 lbs front left, 17 lbs front right and 26 lbs in the rear.

Have started with 30 in the back and 25 in the front, but was not comfortable, and with the poor road quality we have, developped some rattles. I even have some play in the front right top A-arm rearward bushing. So be careful if running high pressure.

P.S. ....I even went as low as 9psi in the front and 18 in the back. Riding hard in the twisties never broke the bead seal, but I could feel the tire rolling under lateral loads pressure. Comfort was not any better .

Let's get back on target

The OP asked an interesting question. He wanted to know what tire pressure folks are recommending for the front tires on an RT if they are running automobile tires. The few folks so far that have given him an answer seem to be running really high pressures on the front and I, for one, am curious to know why that is.

For the front tires, the owner's manuals recommend 15 psi for the 998 RT, and 20 psi for the 1330 RT. But that's with the OEM Kenda tires with the soft sidewalls. Mike is correct that "real" automobile tires wouldn't need as much air as the Kendas given the same weight load, and in fact would perform better with less air. So I'm curious as to why folks are putting so much air in their front tires? When I upgrade my front tires to automobile tires, I would anticipate starting them out at about 13-14 psi and experimenting from there. (I have a 998 RT. With a 1330, I'd probably recommend starting at about 16 psi and going up or down from there, but I cannot speak from experience about that.)

You should be ashamed of yourself. :yikes:

And as for Mike, HE is not to blame. I think his "evil twin" got on his computer again.

Sorry for stiring the pot. I get caught up in the entertainment.

I've been working on getting the front pressure where I like it. I've been running 22 psi and will probably go a bit lower but not much. I like the more positive feel of the higher pressure. I'm sure I'll adjust some more but with the weather closing in and recent surgery riding for this season is done.The KH16 works really well for me in the wet at 22 psi

We think Like Richard, but different - 18 front, 24 rear at 70F

After experimenting on wet and dry all summer, with Kumho KH16 (175/55R15)in the front, and Kumho AST (225/50R15)I. settled down to 16.5 lbs front left, 17 lbs front right and 26 lbs in the rear.

We also run the Kumho Solus KH16 but the 155/60 width on the front on our 15 RT which is about 200 lbs heavier than his ST. My wife puts all the miles (about 20,000 per year) and is only about 100 lb. Since we are interested in mileage and wear, we run 18 psi on the fronts, and we now have 23.5 psi in the rear Kumho Ecsta AST 225 which has over 28,000 miles on it and will run probably another 8-10,000 into next summer. We run the backcountry roads at 3-5 mph over the limit, and the interstate at the limit. Just finished the week, 1900 miles with 600 of it interstate. We could run less pressure on these tires but get better wear it seems and good handling, and my wife can still muscle the front steering on low speed maneuvering. Your ride and expectations are sure to be different.

Higher pressures DO give a more precise feeling up front...

Right up until they start transmitting every surface irregularity back to your hands.
When you get the impression that the tires are starting to get "bouncy"; it's time to lower the pressures a bit.

Rob ride with what you feel comfortable with, but consider what I said above about what a car tire is built to handle ( weight wise ). You say you are larger than most and think adding a few pounds to compensate is a good idea....... Well you need to look at it as a % of the load capability vs. what you consider to be a heavier load ( you ). If you are 100 lb. more than avg. adding 3 lbs pressure is way more than needed if you consider the weight of the Spyder vs. a Car ( which car tires are made for ).....8oz.might be better ...... and Peter ( in Australia ) may have also explained this fact..... in the wet the SIPES in the tires need to compress and de-compress to work ...... a rock hard tire won't let it do it properly .... and 28 psi may not seem high and isn't for a 4000 lb car , but for a 1000 lb or less Spyder it is. Give it a try at 21psi rear, I promise nothing bad will happen ....... I know this post above is directed at front tires but I'm covering all car tire use with this comment to you ........Mike :thumbup:
