Hi there guys. Need 4 new ones all round and im wondering what is going to give me the most life? Or is it just much of a muchness? To go on a 99 classic. Thanks in advance guys.

This is a strange question. You have to get the right size to fit your wheels, for a start. Are they 205s or 215s?

Well im on 205/45/17 just now but wanted to know if 215/40/17 would last me longer?

A wheel can take a fair few different sizes of tyre.

Not sure if there will be any difference in tyre life just do to such a small difference in size. Driving style will be the defining factor, along with the softness of the tyre. I guess cost is an issue here when you talk about life, so just compare the prices. Popular sizes are cheaper.

I think my classic is currently on 215/45/17. I know I am on the "wrong" size, as the wheels and tyres came from a newage. They are fine though, no fouling. My speedo overreads by about 8-9% (checked on a GPS). So not much difference before I fitted them.

Yeah, im looking at Parada 2's and there is a huge difference in price. I can get 215/40/17's cheaper. Will they do the job?

Should do, I don't see any reason why you cannot take the plunge. Also look at 215/45/17. They are the newage size I believe, work fine on mine.

Am I missing something here? Are you saying that you can put 215 tyres on 205 rims? And if so, why would you want to? As for tyre life, it's the compound that the tyre is made of that determines its life isn't it? (providing that the correct tyre pressures and wheel alignment are observed). Putting the wrong size of tyre on a wheel seems to me to be one of the most pointless things you can do, considering that the correct sizes are so freely available. I await education.

i have never heard of a 215 or 205 rim...

Rims are diameter then width, such as 17 x 7 etc.

As far as I know rims don't come that accurately sized. When you look for aftermarket wheels nearly all come in one of several standard widths. You can then fit many different sized tyres within a certain range.

A wider tyre will give more grip, but if its a more popular tyre then there can be substantial cost savings.

I know the rims I got for my 106 could happily take 185-215 without any issue at all. I never looked into it more as the max I could fit under my arches without modification was 195.

Yes, the tyre sizes are metric in width and imperial in diameter. 7" is 175mm approximately. The middle number of the tyre size is the percentage of the wheel's width allocated to the tyre.

I put RE070's on my newage rims, which are 215, the standard width is 205 without a problem

swapped from pirelli 205/45/17 to toyo t1-r 215/40/17 and noticed the difference straight away. more grip and obviously more tyre on the road due to an extra 10mm on each wheel width
