Hi, I currently have 2 almost bald 235/40/18 tyres on the front of my car. Iv been offered 2 tyres at a really good price but there a slightly different size. There 225/45/18, would that be ok to run on my car or would this cause any issues? thanks, david
if you've got the r26 alloys you need 235/40/18 as the recommended size, the 225 wheels are fine with 225/40/18, the tyres you've quoted are too small width wise and to high profile wise.
There's no issues fitment wise but as said recommended size is 235. I currently run 225's on R26 wheels and had no issue but these are a 40 profile not 45 like yours.
These are the wheels I have... I dont track the car or drive it particularly hard so I'm not too fussed about it handling like a go kart. Is 225/45/18 a definite no no or is it ok for general day to day driving?
Worth considering that any deviation from manufacturer recommendations may affect insurance. Maybe someone one on here works for an insurer who could comment ...
Right thanks for the replies guys. Obviously the general view is its a no go so il leave it. Thanks again
225/40/18 or 235/40/18 are both acceptable for an 8j wheel which you have with the 235 the recommended, the 45 profile is the wrong part
This is a sad thread. Have R26 prices dropped so low anyone can afford to buy one without a thought to on going care and maintenance? Anyone who buys this car and doesn't care about the handling or how the tyres will impact that has the wrong car.
So the fact I have asked a genuine question with regards to tyre sizes gives you the right to judge me and the car I own? If you look at post #10 I have opted against the tyres after people's feedback recommending me to avoid them and get the 235/40/18. Didn't really expect to get any stick for asking for abit or help and advice on a so called friendly forum. Thanks to everyone who was kind enough to point me in the right direction however, it's appreciated.
When you say you're not too fussed about the handling, it really infers you're looking for the cheapest option which is the smaller size tyre available to you. It's just the start of a downward circle of maintenance and cheaping out on repairs and replacements etc which drives values down
In this instance, when we put it back into context, yes. If someone is willing to sacrifice some of the characteristics of the car in order to save a few quid, it's indicative of the type of care it's likely to receive.
Moi have never heard so much bullshit. So if some one went down to 225 and put ps cups on it your wrecking it. Wow
I think this started when people started fitting 225 40 to the r26. You are supposed to change a setting in clip if you have 224 40 as opposed to 235 50. Has anyone done this?
Again you're focusing in too narrow here and creating your own example to justify it. The problem is actively not minding that it will have a detrimental affect on the car, because it's cheaper. Would you be happy buying a car where the owners attitude was 'Well it wasn't quite as good as before but hey, I saved £80 on that job!'.
No offence but get real. The dci 175 cups have the same r26 alloys and 225 40's are recommended. Either 225 or 235 40's are completely fine. It in no way will have a detrimental effect if it's a decent make of tyre. 225 45's would fit just fine but have a slightly higher sidewall, not dissimilar to the 235 40's
No thats the eariler 8 spoke sport 225 rims. Base spec dci 175's came with the 17 inch alloys as fitted to the clio 197 which are 7.5j I think?
Yes I think its all for better fuel economy. Even the fitting the 225 40's on the cup rims was for that reason.
No offence taken, but you completely missed my point. But I'll roll with yours anyway. You're saying that there is absolutely 0 difference between 225 and 235 tyres? Physically they offer exactly the same properties?
There is a difference of -8mm (-1.24%) in diameter betweeen 235 40 18 and 225 40 18. There is a difference of +15mm (+2.33%) in diameter between 235 40 18 and 225 45 18. Ironically, the 225 45s, would probably lead to the speedo reading bang on as it over reads a little
Out of curiosity what size tyres are recommended for the r26r? I belive the toyos are 225 40'S So are you saying renault are in the wrong for recommending 225 40's for the megane 225, dci 175 and r26r? I never said there wasnt a difference. The difference is neither here nor there 225 x 40 = diameter 225mm ,sidewall height (including seating bead) 90mm 235 x 40 = diameter 235mm, sidewall height 94mm So 10mm wider and 4mm higher . Totaly dependent on the make and style of tyre. The sidewall height of the 225 45 is 10mm higher than the 225 40 and 6mm higher than the 235 40. 225 40's and 235 40's are completely fine on the 18" cup rims regardless which variation of megane sport it may be. It doesn't make you a bad owner if you run 225's. And its certainly not that which is driving down the value of meganes.
lol this is getting a bit daft now. an 8j rim is recommended to use 235 but can use a 225 or even 245.
Hi, I think the R26R may have a different kerb weight / suspension set up. Same with the DCI so I don't find these comparisons useful. You're exact quote is 'it in no way will have a detrimental effect'. The fact is that it will offer a reduced level of grip, which in turn will reduce cornering speed & acceleration out of corners. So it will have a detrimental effect. Besides my original point still stands, which wasn't regarding the characteristics of different tyres on the r26. Regardless of what the item is, an owner says they're 'willing to sacrifice any characteristic of the car to save money' is generally a bad sign. Intention is often as bad as action.
'll So a r888 at 225 40 will have a reduced amount of grip compared to a regular tyre at 235 40? The r26r is lighter than the r26. The dci is heavier and both are recommended to be fitted with 225 40's why? R888 tyres at 225 profile are a lot more expensive than your average 235 tyres
I see your point but you can't make that comparison with td tyres and road tyres, 225 r888's are recommended for an 8j where as a 235 road tyre is recommend for a 8j too
Exactly salty. Both sizes are recommended. As long as there decent tyres the differences in handling is unnoticeable. Its totally down to the quality of tyre According to Wikipedia the dci 175 cup should be fitted with 225 45 profile tyres. So if that is correct im running the wrong size
do u seriously think my 235 tyres will grip more than his 225 tyres?? sorry to join in but this conversation sucks bum and angers me abit. u get some 255 budgets and ill drive on some 205 michelins, lets see who grips more.
