ostego Posted March 5, 2014 Share Posted March 5, 2014 Have noticed my front tyres are looking a bit deflated, know i cant refer to the manual as theyre not stock Have seen the sticky saying to put them at 35psi and work my way up... but what sort of signs should i be looking out for to let me know ive got the right sort of psi? Should i bring all tyres to the same psi or is it recommended to vary it between the front and rear? They say 50psi max on the tyres.... but think that is a bit overkill!

350 Russ Posted March 5, 2014 Share Posted March 5, 2014 32 all round. Quote Link to comment Share on other sites More sharing options...
Neilp Posted March 5, 2014 Share Posted March 5, 2014 32 all round. Far too soft tbh. 35 all round should be fine for most tyre sizes on normal road driving. 1 Quote Link to comment Share on other sites More sharing options...
ostego Posted March 5, 2014 Author Share Posted March 5, 2014 24.5"??? I think you may have you're numbers mixed up dude 24.5 diameter from my measuring tape! Will go for 35 all round then, as long as it wont do any harm! Quote Link to comment Share on other sites More sharing options...
ostego Posted March 6, 2014 Author Share Posted March 6, 2014 So i go to pump up my tyres and put the first one from 26 psi to 35 psi.... go to do the rest and cant get the metal cap off them no matter how hard i try... have used plyers a 10mm wrench and wd40 and those ****ers are not budging.... anyone know a remedy for this? Or is it a case of an expensive visit to a tyre shop? Quote Link to comment Share on other sites More sharing options...
Ekona Posted March 6, 2014 Share Posted March 6, 2014 Wait, what are you doing? Or trying to do? Remove valve cap. Pump up to 35psi, as indicated on pump gauge. Replace cap. It's the easiest thing in the world to do on cars, except filling the fuel tank. Quote Link to comment Share on other sites More sharing options...

ostego Posted March 6, 2014 Author Share Posted March 6, 2014 Its not that difficult.... i have metal dust caps that must be removed in order to attach the pump to the tyre.... much in the same way one would unscrew the dust caps on a bike tyre to pump them up and get at the valve.... 3 of my 4 metal dust caps are simply impossible to unscrew.... i have tried unscrewing them with tools and using wd40 in an attempt to loosen them.... but they are stuck firm so i cannot now pump up my remaining 3 tyres Quote Link to comment Share on other sites More sharing options...

Ekona Posted March 6, 2014 Share Posted March 6, 2014 Right, basically someone has fitted cheap-ass caps to your valves that have seized on. Now you have to go to a tyre fitters, get them cut off and new ones put on. I still don't get what you're measuring. Quote Link to comment Share on other sites More sharing options...
leonk Posted March 6, 2014 Share Posted March 6, 2014 (edited) Back to the valve caps..... Are they round or nut shaped? If they are nut shaped they may have a little allen key grub screw in them as an anti theft deterrent. If not try holding the stem of the valve with grips and the cap with a spanner/grips. Don't go mad though as you can snap the end of the valve off! I assume these are your wheels from a previous thread.

Edit plus what Dan says Theyre nut shaped... tried REALLY hard to get the off... using pliers and a screwdriver with a 10mm nut head adaptor thing.... think i may have put the rubber under a lot of stress, so dont want to try any harder. Any idea how much it would cost me to get the valves replaced? Quote Link to comment Share on other sites More sharing options...

Cant see it... so i used a measuring tape just to measure the diameter of the tyre from one side to the other.... know its not the right way but its just what i did!

Lexx Posted March 6, 2014 Share Posted March 6, 2014 · Hidden by Lexx, March 6, 2014 - f Hidden by Lexx, March 6, 2014 - f From what I can gather, you are trying to measure the height of your tyre wall from the floor in an attempt to gather what pressure the 3 tyres you cannot get the caps off are in comparison to the one you can. If this is the case, you sir are an eejit. Link to comment
Lexx Posted March 6, 2014 Share Posted March 6, 2014 Are you referring the what is written on the side of your tyre? ie 245/35/18 or whatever? If so, you need to go do some Googling. the 35 part is not a measurement directly. It's a percentage of the 245 width. More to the point, it has feck all to do with tyre pressure.

ostego Posted March 6, 2014 Author Share Posted March 6, 2014 By 35 i mean psi By 20.5 i mean the diameter of the wheel in inches By 24.5 i mean the distance between one outer edge of the tyre to the other (2 inches of tyre on either side of the wheel) in inches Am sorry for all of the confusion vreated by this.... but it is no longer relevant. I have decided to go for 35psi pressure but am now faced with 3 stuck dust caps Quote Link to comment Share on other sites More sharing options...
leonk Posted March 6, 2014 Share Posted March 6, 2014 (edited) Just for future reference, the best way to measure the pressure is with a pressure guage. As you are not mechanically minded, the best thing to do is get to a tyre fitters and get new valves. This is going to cost between £10 and £15 pounds per wheel. Better this than end up with a bigger problem because you can't get air in or check the pressures. Edited March 6, 2014 by leonk Quote Link to comment Share on other sites More sharing options...

Ooh, fair shout... didnt really know tbh.... was assuming that if the wheel was bigger, it may mean the pressure would need to be different from that with a smaller wheel given the lower volume of air that can be fitted in the tyre... but i guess the nature of pressure as a unit makes that irrelevant thinking about it! Was just trying to be thorough... not purposely trying to drive everyone mad ! Edited March 6, 2014 by ostego Quote Link to comment Share on other sites More sharing options...
