Hi Guys n Gals, Iv'e just bought a new set of rims they have tyres fitted, all 4four are 245/45/18, will these wheels fit on my Z with these tyres? if not what size should i fit........All 4 wheels are 18x8j offset is 38. thanks in advance Jay :dance:

 

8j is ok for the fronts, but ideally you want 8.5j+ for the rears...... (9.5j is a common width)

 

(standard 16" UK rears are 8.5j)

 

Also a 38 offset with a 8j width will leave the wheels sitting too far in the arches, rather than nice and flush.

 

I would stick 235's on the front and 265's on the rear

As Legrath has already given you probably the best tyre size combination, I will just add that normally on the 300ZX the best handling and appearance is obtained by having wider wheels on the back.

This was how the UK 300ZXs were supplied.

Buying a set of wheels all the same size (in my opinion) is not a good idea. They may be cheaper to buy but in the bigger picture of handling,grip and appearance it is false economy.

45 profile is too big, overall diameter is 3.5% out, should be 40 profile

Hi pete, when i bought them i was told they were all 8.5j which would have been ok for the the tyre sizes Legrath mentioned but when the wheels turned up tey were 8j so theyre gonna have to do till i buy 2 new rears..........i was thinking of 225 on the front and 245 on the rear for the time being.... do you guys think this will be ok? thanks Jay

Hi Legrath ichecked tyre size calculator this morning on rochford tyres and it says 245's max on 8j rims is this correct? or is it possible to fit 265's without any problems... Thanks Jay

Ive fitted 255 on 8" rims before 265 should be ok .Id go 255 rears and 235 front .You could aways use a 15mm bolt on spacer all round with them offsets aswell to push the rims out from inside the arches maybe a 20mm bolt on .Driftworks do a bolt on spacer kit with interchangable widths its on there website you can try diffrent variations.
