The bicycle tire pumps are basically the same, some are now double action, but quite a bit of muscle effort is still required. The frame pumps have also changed very little. The go ole days of distance bike rides

Depending on the size why not a Bridgestone Driveguard or Pirelli in a runflat?

 

I rather use an automated pump in case of emergencies than pumping air in tire. Has anyone attempted to trying using the manual pump on car tire?

 

Not on a runflat, but I've used an ordinary old bicycle pump to fill up a car tire. It's really not as hard as you might think.

 

Back not too long ago I exclusively used a cheap, basic bicycle pump to maintain / adjust the tire pressures for the cars in my household. I got so good at it that I knew exactly how many pumps it takes to raise the pressure the desired amount by specific size of tire. Take a reading, oh, its 2.5psi low on a 19" tire, that will take exactly 27 pumps. I did have a small air compressor but it took 3 or 4 minutes to come up to pressure so the bicycle pump was just a lot faster. Then I got lazy and bought a 20V Dewalt portable unit, but indeed, bicycle pumps can do the job if you have decent mobility.

 

The simple comparison to the volume per stroke of a long hand pump and a 12 volt or any other 'small' electric pump is clearly in the hand pumps favour. These little pumps may sound like they're doing herculian work when in fact there's typically a little piston the size of a quarter maybe going like heck for what seems like 5 + minutes to give you an added 2 psi gain. I recently bought a new battery operated pump that's about 1/2 size of a typical clay brick and it has ability to do a preset stop at desired psi. Well I fully charged it and needed to put 3 psi in each of my 4 tires. It did the first one and maybe 1 psi in the second one and ..... died! Had to go charge it up for about 1/2 hour to do next tire! . It would work great for a basketball maybe, but to ask it to get to 34 psi was a little too much for it to handle. Oh well I got it on sale 50% off for $20. I've still got my trusted 20 year old hand pump with a dial gauge that works great! And I don't take 1/2 hour to recharge 'my jets'.

 

Reminds me of the last time I bought new tires from Costco. Came to pick up the car, went outside and, 1 tire flat (turned out the new valve stem they put on that rim was defective). Anyway, the service person came out to take the car back in, bringing one of those 12V socket air pumps as they didn't want to drive a brand new tire flat of course. Even with the engine running to keep voltage high it still took for freaking ever. Now, my 20V DeWalt pump, I have 4 cars in the driveway so when I check pressures that's 16 tires to check and adjust. it can handle all 16, probably 15 to 30 seconds to add 1 to 4psi (typically) to each tire and when done, still shows almost full charge left (with the bigger 5ah DeWalt batteries). The downside is its a lot more expensive compared with most portable air pumps available but certainly the ability to set and forget the desired pressure is a thing of beauty.

 

Actually curious if anyone has replaced with another run flat, brand etc and if they’ve noticed any improvements over stock Bridgestones.
Local driving not an issue with run flats. Trips though different.

 

Yes see #10 https://www.clublexus.com/forums/nx-...l#post11953560 on this thread @fred430

I replaced my stock runflats (what a terrible tire!) with runflats from Continental which I've had for 10 months now and enjoy a lot. The traction is much better than stock, and I like the security of runflats as a lot of my driving is on narrow urban highways. These come in 18" that fit the NX. They do not have a 20" size that works so I bought 19" wheels from TireRack and a 19" version of their runflat. Bottom line -- if you have 18" wheels and want runflats I think these are worth considering. Noticeably better traction than stock, no impact on gas mileage, treadwear hard to tell as I've only put 10K miles on them ... best guess is they will last a little longer than the stock but not a lot (I replaced my stock tires at ~25K miles as I couldn't wait to get rid of them).

I've tried to link the post but not sure if I am doing it right ...

Do you have the or the ?

 

This is for NX350 with 18s.

All RFTs are terrible : Heavier, less mpg, noisier, poorer handling, less overall tread life. ...but there are a whole lot of threads already discussing non-RFTs and RFTs.

P.S.- RFTs have been recently renamed "Tire Store Hobblers"

 

Well, your disclaimer is YMMV. I’ll come back with YRPMD – Your Relative Preferences May Differ. If I was retired and driving on mostly newer roads with wider shoulders in a warm climate I would prefer to switch to CrossClimate and forego runflat. That’s not my situation as I commute in and out of a Northeast city on busy roads. Imagine yourself after a long workday driving home on a 35 degree rainy night hitting a new pothole that was covered in a puddle at speed and having an immediate full blowout on a low-profile tire (my former Lexus RX with CrossClimate tires) and needing to pull over on an urban highway without a full shoulder and putting your hazards on in the dark with cars buzzing by you while you call service and wait. A bicycle pump is not going to make your evening any more pleasant. For my preference set …
Traction – very important to me and the stock Bridgestone had the worst traction of any tire I can remember. The Continental runflats I have are much better – not as good as CrossClimate but good enough that I consider them fine. That’s a huge difference on the most important attribute to me.
Runflat – as noted, for my driving and lifestyle I like having the peace of mind of runflats. I understand that you can’t patch runflats in the same way and I might need to replace all of them depending on the situation – I’m fine with that on the chance it occurs.
Treadlife – I agree, runflats seem consistently much worse in this department. Too soon to know on my Conti’s but I’d stipulate that they have noticeably lower treadlife. For my preference set the cost isn’t a big issue so I’m mildly annoyed but that’s it.
Noise – I don’t notice an issue. Maybe my ears are less sensitive than others and/or the roads I drive on are bad and I always have the excellent Mark Levinson on … whatever it’s not something I notice.
MPG / Weight – MPG in my 350H is excellent … perhaps it would be 1 or 2 MPG higher with a Cross Climate, although if I added a Modern Spare it would add weight in the car (different impacts than on the tires of course – and also would use up cargo room). Given the already great MPG this is pretty low on the list.

Bottom line is that most people might have a preference set pushing them away from any runflat. But for what I care about runflats do differ and the prior Bridgestones were terrible and I’m a happy camper with my Conti’s.

RFTs are no good in a full blowout - SORRY. RFTs are so misunderstood and most people are truly ignorant of what RFTs actually provide. Please remember ignorant does not mean stupid, only that a person is not informed of the actual facts and knowledge. No tire works or is drivable after a full-blowout RFT or non-RFT.

So peace to you brother if you like RFTs and think RFTs will solve your situation r give you more calmness and comfort in driving.

P.S. my YMMV parting signature and is sometimes misunderstood. I was always interested in performance cars but at the same time also liked high mpg cars. The NX hybrid is my second favorite high mpg car and performance cars seem to be fading
