265/50/r14

[heavyd]

anyone use this big of a tire in the rear on the stock p type rims? if so does it look redneck... like hella bad sticking out or not that bad of fitment

[Chris Sullins(STIX)]

Im running 235/60/14 LeMans and there is just about to much sidewall bulge..Anymore and they would look like baloons...

nope......

[Supra_devil]

245/50r14's look sweet on p types. i really don't know if 265's will fit but i would lean towards no.

[Ryley]

265s do fit, a few guys here in aus had them on. mind you, you will probably get a shitload of sidewall flex and handling will probably be compromised.

i had old, worn out 245 tyres on my 7mgte supra, and then replaced them with 225 yokohamas and the traction difference was unbelievable....

Phil here in Toronto drove a car with 265s on it. said the car was helacious to drive. If you stepped on the gas the sidwalls would do something weird and the car would turn...like the whole car shifts across the road. If you let go of the gas it would go back to normal. He said you were constantly correcting and couldn't really drive it at all. Corners were just a bad idea.

I get a 135mm sidewall height on a 225/60 and 133mm height for a 265/50...so there is basically no difference in that regard. You will probably have rubbing issues, but is should handle the same or better than stock if 265s would even fit on the 14x7s.

I don't think you would get 265/50's on the stock rim. 265/60's go on the rim only because you have a whole lot more sidewall distance to angle in from the tread to the wheel, and 60's series tires are not usually as stiff of a sidewall as 50's. But I think 265/60's would rub with stock suspension and would be usefull only for straight line apps.
Your choices for wider tires on the stock wheel are:
A) increase the sidewall height (235/60 or 245/60)
B) Reduce the sidewall height (245/50 gives the same sidewall height as 205/60)
C) Find a 245/55 or fit a 265/50 to maintain the same sidewall height (Good Luck)

ok i have to say this but 215 fit great 225 if you are pushing it

a 245/50 is the same height (actually a bit shorter than) 225/60 it is off by 3.8% so at 60mph on the speedo you would be going 58 mph.
a 205/60 is way smaller, 10% smaller than stock.

[MWebber]

uhhh..... :nono:

225 IS the stock size(P-type)... how are you "pushing it"..... 235/245 THEN, you are pushing it....


*sigh*

[85supra_ftw]

265 is way too wide for the stock rims 245/60 is the max recomended width from bfg and goodyear on the 7 inch rim. even a 245/50 isnt recomended due to the tread width differnce between 50's and 60's. If you want to run that wide you'll have to invest in some new rims.

I would recomend running higher priced rubber (like some yoko's) at the stock 225/60 size instead of less expensive oversized ones.

the way the rim and tire work together (sidewall flex) changes as the width of the rubber moves from being exen with the rim edges to hanging over. That is why the guy runnign 265's had a loose back end and found it difficult/unpredictable the sidewalls were actually flexing under the torque of acceleration and twisting under hte car.

I may have just stated the most blatantly obvious stuff here but Im tired and I'm pretty sure Ive picked up the flu someplace :( Sorry

BF Goodrich 225/60R14 has a diameter of 24.7" for 842 revs/mile at 45mph
BF Goodrich 245/50R14 has a diameter of 23.7" for 878 revs/mile at 45mph
BF Goodrich 205/60R14 has a diameter of 23.7" for 878 revs/mile at 45 mph

This data is from the BFGoodrich site. But because sidewall height =width x aspect ratio (245 x 50 percent or 205 x 60 percent), this will be true for all brands in these sizes, unless the size is an approximation.

245/50r14 according to the tire size calculator i use is 3.8% shorter, yes it is almost an inch, but thats doesn't matter. 3.8% off on your speedo is acceptable.
the exact measurement is less important than the %age in this case.

also the specs they give are:
818.7 revs per mile with a 225/60r14
851.4 revs per mile with a 245/50r14
the 205 is the same as the 245, i must have made a mistake when doing it before.


not all brands tires are the same and this is why my numbers are by math only and yours are for BFG brand tires. this is why our ##'s are different.

[joefoe]

past 225 on a 7" rim all you gain is side wall bulge, plus 265 on a 7" rim is way past the min rim width tire companys have min rim widths for a reason!

[pituala]

I drag race, no raod racing or auto-x, so I went with the BFG 245/60r14's and they're great, and look great too. I'll go take a pic and post it.

[pituala]

Ok, here are the pics

yeah how come only pituala is talking about BFG 245/60-14s?? I've had them about 3k miles, they look great and tractions good and they fit perfectly. cornering isnt spectacular but is the mk2 known for that anyway?

[scorpmatt]

this is a little OT but, when I bought my 83 l-type it has some funky 14 steelies (thinking they are froma cessida, not sure) with 185/70/14s on it. how far off is my speedo going to be with that? Am in the process of purchasing the p-type rims and the proper 225/60/14s for them.

Measure the tire heights and you can figure it out easily.

And I just pulled a 2.05 60' time at the drag strip with them with no working tachometer!

Alright, I'm a bit of a noob when it comes to that. how exactly can you figure out the heights of tires from the numbers they give you?

Just measure the height from the ground up to the top of the tire with a tape measure ;)

well that works for what I have one there, but what the stock tire heights?

[pituala]

I've only measured my rear tires, but I think 225/60 14's are about 24.62" tall by my calculations.

[KurtW85]

alright, look

get the circumfrence, I think the formula is: D*2(3.14)=Circum.
Divid a mile/km by the circum. and thats how many revs. per mile.
I dont know how to figure out the speedo issue, someone will.

[lechner]

Alright, I'm a bit of a noob when it comes to that. how exactly can you figure out the heights of tires from the numbers they give you?To figure the height of say a 225/60/14, 225 mm width x 60% aspect ratio gives you 225x.6=135 mm sidewall height. If you want the height from the ground to the top of the tire, multiply that by 2 (since you have 135 mm of sidewall below the wheel and another 135 mm of sidewall above the wheel) and add this to the 14" wheel size (remember to convert mm to inches or vice versa). Measuring with a tape measure will result in a too small number due to deflection or flattening caused by the weight of the car and dependent upon the air pressure.

wow, thanks a heap! just found out that the tires I have now are 614.6 and the stock rims, l-type are 628.6, the p-type are 625.6. :(
